Signal Definitions
All hardware alarm signals (Fault, PFW, OTW, Power Capacity) are open drain FETs. These signals should 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. Contact your GE Energy
representative for more details.

Description
If shorted to LOGIC_GRD, the rectifier output is enabled when using I 2 C mode of operation. May also
be toggled to reset a latched OFF rectifier. Function not available in RS485 mode.
An open drain FET; normally HI, indicating output power is present. Changes to LO at least 5msec
before the output voltage decays below 40Vdc.
Interrupt signal via I 2 C lines indicating that service is requested from the host controller. This signal
pin is pulled up to 3.3V via a 10kΩ resistor and switches to active LO when an interrupt occurs.
Indicates that an internal fault exists. An open drain FET; normally HI, changes to LO.
Short pin, see Status and Control description for further information on this signal.
Short pin, connects last and breaks first; used to activate and deactivate output during hot-insertion
and extraction, respectively. Ref: Vout ( - )
See Status and Control description for further information on this signal. Ref: Vout ( - ).
Allows changing of output voltage through an analog voltage input or via resistor divider.
An open drain FET; normally HI, changes to LO approximately 5°C prior to thermal shutdown.
Open drain FET; Used to indicate rectifier operation mode; HI indicates 2725W operation and LO
indicates 1200W operation.
Voltage level addressing of rectifiers within a single shelf. Ref: Vout ( - ).
Voltage level addressing of rectifiers within multiple shelves. Ref: Vout ( - ).
Diode OR’ed 8Vdc drain; used to back bias microprocessors and DSP of failed rectifier from
operating rectifiers. Ref: Vout ( - ).
Resets the I 2 C lines to I 2 C line 0.
5V at 0.75A provided for external use by either adjacent power supplies or the using system.
A single wire interface between each of the power unit forces them to share the load current. Ref:
Vout ( - ).
