CP2000AC54TE CPL High Efficiency Rectifier
100-120/200-277VAC input; Default Outputs: ±54VDC @ 2000W, 5VDC @ 4W
Table 3: Signal Definitions
All hardware alarm signals (Fault, PFW, OTW, Power Capacity) are open drain FETs. These signals need to be pulled HI to either 3.3V or 5V.
Maximum sink current 5mA. An active LO signal (< 0.4VDC) state. All signals are referenced to Logic_GRD unless otherwise stated.

Output Short pin, see Status and Control description for further information on this signal.
Input Short pin, controls main output during hot-insertion and extraction. Ref: Vout ( - )
Input Selects operational mode. Ref: Vout ( - ). No-connect PMBus, 10kΩ - RS485
Input Changes the default set point of the main output.
Output Open drain FET; normally HI, changes to LO 5°C prior to thermal shutdown.
Output Open drain FET; HI indicates 2000W operation and LO indicates 1200W operation.
