Features Input voltage range: -38 V to -72 V, output power: 2200 W Efficiency: 94% (Vin = -53.5 V, 40% load) Depth x Width x Height: 485.0 mm x106.5 mm x 41.0 mm (19.094in. x 4.193in. x 1.614 in.) Weight: ≤ 3.0 kg Hold up time: 8 ms Hot-swappable With speed-controllable fan Support input undervoltage, reverse polarity protection Support output overvoltage, current limiting, short circuit, fault isolation protection Support overtemperature protection, fan fault protection CAN communication interface for controlling, programming and monitoring TUV, UL, CE certification and CB report Meet IEC 62368-1, RoHS6 requirement Application： Routers/Switches Servers/Storages Telecommunications equipment Current Share： Up to 32 PDC-2200WCs can be paralleled for redundant configurations. The current sharing is implemented over CAN communication The PSU uses a fan to dissipate heat. The fan draws air in from the front and exhausts air out of the rear for cooling, and adjusts its speed based on temperature control.
