Input

Input voltage 3 AC 400...500 V, ± 15 %

47-63 Hz, Suitable for IT power systems

Rated Tolerances

• Continuous operation

• Short term (1 min) at 24 V/30 A

Input current 3 x 2.0 A

Inrush current < 17 A bei 576 V AC

Inrush current limiting done with a fixed 47R resistor (not a thermistor) which is bridged after the unit is running, so losses are minimised. That means no reset time even at a warm-start.

Fuse loading < 2 A

To be fused with a 3 x 10A, B-type 'circuit-breaker' switch based on the usual thermomagnetic overload sensing principle (used anyway to fuse the input lines; unit has no internal fuses).

To achieve current sharing the output V/I characteristic can be altered to be 'softer' (25V at 0.4A, 24V at 30A). This is done by repositioning a bridge connection (without opening the unit).

Design advantages:

• All connection blocks are easy to reach as mounted at the front panel.

• PVC insulated cable can be used for all connections, as the connection blocks are mounted in the cooler area on the underside of the unit.

The V/I characteristic of the supply is straight.

Advantages of the switch-on/overload behaviour:

• Safer switch-on into highly non-linear loads with large starting currents

• Short-term overloads result in current limiting and not in an immediate shut-down.

• Parallel operation of several units possible. Proper switch-on performance is obtained.
