POWER CONTROL CENTER / POWER DISTRIBUTION BOARDS (INDOOR TYPE)
A Power Control Center/distribution board (also known as panel board or breaker panel) is a component of an electricity supply system which divides an electrical power feed into subsidiary circuits, while providing a protective fuse or circuit breaker for each circuit, in a common enclosure. Normally, a main switch (SFU) or air circuit breaker (ACB) or Moulded case circuit breaker (MCCB) and in recent boards, one or more residual-current device (RCD) or residual current breakers with over current protection (RCBO) and miniature circuit breaker (MCB) are also incorporated. Various types of metering equipments are used to monitor the input and output of feed and subsidiary circuits such as volt meter, ampere meter with phase selector switches, indicators for each phase, fuses for protection, frequency meter, multifunction meters, kwh meters etc. Distribution boards are also referred to as a: Breaker Panel Circuit Breaker Panel Consumer Unit, Or Cu Electrical Panel Fuse Board Electric Board Fuse Box Breaker Box Load Centre/center Panel Board Power Breaker Service Panel Db Board ACDB (alternating current distribution board) DCDB (direct current distribution board)

MOTOR CONTROL CENTER A motor control center (MCC) is an assembly of one or more enclosed sections having a common power bus and principally containing motor control units. Motor control centers are in modern practice a factory assembly of several motor starters. A motor control center can include variable frequency drives, programmable controllers, and metering and may also be the electrical service entrance for the building. Motor control centers are usually used for low voltage three-phase alternating current motors from 208 V to 600 V. A motor control center consists of one or more vertical metal cabinet sections with power bus, contactor or a solidstate motor controller, overload relays to protect the motor, fuses or a circuit breaker to provide short-circuit protection, and a disconnecting switch to isolate the motor circuit. Threephase/single phase power enters each controller through separable connectors. The motor is wired to terminals in the controller. Motor control centers provide wire ways for field control and power cables. Each motor controller in an MCC can be specified with a range of options such as separate control transformers, pilot lamps, control switches, extra control terminal blocks, various types of thermal or solid-state overload protection relays, or various classes of power fuses or types of circuit breakers. A motor control center can either be supplied ready for the customer to connect all field wiring, or can be an engineered assembly with internal control and interlocking wiring to a central control terminal panel board or programmable controller.

AUTO MANUAL FAILURE (AMF) PANEL BOARD
Auto mains failure (AMF) panel is meant for controlling DG START / STOP sequence in accordance to the availability of main power supply. We design & manufacture the AMF panels for various capacity & different make of Diesel Generator set. AMF panel is the short form of Auto Mains Failure panel. It is normally connected to the generator set to control the generator set function. It is connected with a feedback from main power source so that it senses if the main power fails and triggers a start command (through relay and hard wiring) to the Generator to start and close the necessary circuit breakers to take the load on to Generator. It can perform the same function vice-versa, when the main supply is restored or is available it transfers the load to main supply and sends closing command to the DG Set so that the generator stops and is ready to perform the same function again when required. It is also provided with a smart battery charging system for the generator so that the starting of the generator is not hampered for low battery voltage and also provides protection to the battery against excessive charging. Manual or operator's intervention will not be needed to start the generator set after the power is failed from main source. AMF control system provides Consistent power supply to the load in absence of main supply. DG set protections Smooth Start / Stop Sequence. Audio visual indications of various fault conditions. Protects the load from voltage fluctuations. Auto / Manual modes of operation. Mains failure and voltage fluctuations detection. User friendly.

AUTO POWER FACTOR CORRECTOR (APFC) PANEL BOARD
An Automatic Power Factor Correction (Controller) panel is used to Save Energy by consistently maintaining higher power factor. Low Power Factor leads to poor power efficiency, thereby increasing the apparent power drawn from the distribution network. This results in overloading of Transformer, Bus bars, Switch gears, Cables and other distribution devices within the Industry or consumer area. With an APFC panel the energy producer can: Avoid Penalization for lower power factor. Enjoy incentives for higher power factor operation being extended to Industries by some Electricity Boards/ Companies. Optimize the connected load for improved plant load factor. Avoid manual disruption. Avoid high current consumption losses. Improvement in voltage regulation. Decrease Maximum Demand KVA, thus avoiding penalty and Demand Charges. The ratio of Active Power to Apparent Power is called Power Factor. Most of the commercial and Industrial installations in the country have large electrical loads which are severely inductive in nature, such as motors, large machines, air conditioners, drivers etc. This results in a severely lagging power factor. This means loss and wastage of energy and heavy penalties by electricity boards. In case of fixed loads this can be taken care by manual switching of capacitors. However in case of rapidly varying and scattered loads it becomes difficult to maintain a high power factor by manually switching on/off the capacitors in proportion to variation of load within an installation. This drawback is overcome by using an Automatic Power Factor Correction Panel (APFC Panel) which not only maintains a high power factor but also eliminates the need for constant manual intervention. Advantages Economical with faster payback periods Ability to maintain a constant high power factor Eliminates low power factor penalties levied by EB Reduces the KVA demand charges Improves efficiency of the system by reducing losses Prevents leading power factor in the installations during low load conditions

JUNCTION BOX An electrical junction box is a container for electrical connections, usually intended for joining of wire and conceal them from sight and deter tampering. A small metal or plastic junction box may form part of an electrical conduit or thermoplastic-sheathed cable (TPS) wiring system in a building. If designed for surface mounting, it is used mostly in ceilings, under floors or concealed behind an access panel - particularly in domestic or commercial buildings. An appropriate type may be buried in the plaster of a wall (although full concealment is no longer allowed by modern codes and standards) or cast into concrete - with only the cover visible. It includes in-built terminals for the joining of wires.A similar, usually wall mounted, container is used mainly to accommodate switches and sockets.The term junction box may also be used for a larger item, such as a piece of street feeder with busbar for connection of several cables for distribution. Junction boxes form an integral part of a circuit protection system where circuit integrity has to be provided, as for emergency lighting or emergency power lines.
AUTO LOAD SHARING & AUTO SYNCHRONIZING PANEL We offer generator synchronization and load sharing panel controlled through auto synchronizers or full PLC based system for LT generators (415 V) with load sharing. Auto load sharing & auto synchronizing panel is required where the source of energy used are more than two, i.e. main supply and two or more generators. The work of an st auto load sharing & auto sync panel is to start the 1 generator when main supply fails st and transfer the load to generator(as the AMF panel) then it senses the load on the 1 st generator which when increases beyond the output capacity of the 1 generator, it starts nd the 2 generator to fulfill the supply demand effectively. In the same way it also stops the st nd 1 or the 2 generator as per the requirement of the supply demand and also shuts the generators when the main supply is restored. It finds its use in industries, factories, hospitals, malls, multiplexes etc.
