DC Edge[tm] II – Dual Feed 350 A (4/4) Universal DC Power Distribution Unit

Transtector’s Model 350DF 4/4 PDU is a compact high-power/high-current, universal voltage (±24 VDC to

-48 VDC) power panel featuring dual-feed 350 A buses for either primary or secondary power distribution. Model 350DF 4/4 provides power for a wide range of local or remote, wireless and wireline, data and communications applications. The panel fits 19-inch or 23-inch racks.

DC Edge provides four breaker/fuse outputs per bus – up to 125 A per interrupter. Any combination of site-configured interrupters:

– Airpax® LEL single-pole, non-mid-trip breakers up to 100 A;

– Littelfuse TLS fuses, 1 to 125 A; and/or

– Copper Bussmann TPS fuses, 1 to 70 A.

TLS and TPS fuses use telecom fused disconnect (TFD) housings and fuse cartridges manufactured by Canadian Shunt Industries. Breakers, fuses, and TFD assemblies are sold separately by the respective manufacturer.

Buses A and B (input feeds and returns) are mutually isolated, except for the replaceable alarm board which accepts power from either Bus A or B.

The alarm board on the front of the panel contains three LEDs: one for each feed (green for power on and off for power off/failure); and one for the interrupters (off during normal operation and red for a tripped/blown interrupter). Along with the LEDs on the front, Form C dry contacts on the rear provide connectivity to remote audible/visual alarm devices for announcing/displaying power and interrupter failures. Alarm connectors are removable 3 – 40 screw posts for either 22-16 AWG insulated ring lugs (supplied) or bare wire.
