DESCRIPTION

- INH_LO_B -

1

Reference pin to INH_HI_B

Output Inhibit Function

- INH_HI_B -

2

An opto-isolated input with 2-10mA current capability. Apply +(3-15)V on INH_HI_B and

RTN on INH_LO_B (e.g. from the Auxiliary Output 5V) to activate the inhibit function.

INH_HI OPEN OR LOW state ENABLES the module output.

INH_HI HIGH state INHIBIT the module output.

- PG_LO_B -

3

Reference pin to PG_HI_B

Output Good Indication

- PG_HI_B -

4

Open collector output with 20mA pull-down capability, max. 15V (recommended Rpull-

up=1k, Vcc=5V). Referenced to PG_LO_B.

PG_HI open or High state indicates that the module output voltage is below lower regulation

limit. A PG_HI fail state turns the GREEN DC OK LED to RED.

PG_HI LOW state indicates that the module output voltage is within normal operation limits.

10

Open collector output with 20mA pull-down capability, max. 15V (recommended Rpull-

up=1k, Vcc=5V). Referenced to PG_LO_A.

PG_HI open or High state indicates that the module output voltage is below lower regulation

limit. A PG_HI fail state turns the GREEN DC OK LED to RED.

PG_HI LOW state indicates that the module output voltage is within normal operation limits.

LED POSITION

DESCRIPTION

Input AC Good

Front panel – LED2

(see

ON state LED indicates operation within specified input voltage range.

GREEN LED indicator goes to an OFF condition on PFAIL signal failure

state.

Fan Good

Front panel – LED1

(see

ON state LED indicates normal fan operation and no OTP status.

GREEN LED indicator goes to an OFF condition on FAN_FAIL / OTP signal

failure state.

Output Good

Module connector / rear side

(see

GREEN LED indicates that module output voltage is over minimum

regulation limit.

GREEN LED indicator goes to RED on PG_HI signal failure state.
