EcoPower PSS
Technical Data General characteristics The switching power supplies use a FLYBACK converter. The output voltage is regulated with a tolerance of +/- 3 % with a charge variation from 0 to 100% and with input voltage variations (See the limits on the table). • No minimum load required The equipment starts regularly in all the nominal input range with zero load on the output, while maintaining the output voltage within 0,5% of nominal output voltage. • No Hiccup-mode during overload or short circuit The equipment works regularly in constant current mode during overload up to a full short-circuit (zero output voltage), without stopping or going in burst mode (called Hiccup-mode). This condition can be maintained indefinitely without any damage or performance degradation. This feature helps starting loads with high inrush current or great capacitive load. • High stability / high open loop bandwidth and phase margin This features gives very good behavior of the equipment with rapidly changing load (from zero to max load and vice versa) and during start up, without ringing and overshoot. • Operating-condition signaling A LED provides the optical indication of the output voltage: good operation, overload condition, short-circuit condition. • Continuous input voltage The power supplies accept a continuous input voltage from 130VDC to 350VDC.
