Remote ON/OFF Control
The CTRL pin is controlled DC/DC power module to turn on and off, the user must use a switch to control the logic voltage high
or low level of the pin referenced to -INPUT. The switch can be open collector transistor, FET and Photo-Couple. The switch must
be capable of sinking up to 1 mA at low-level logic voltage. High-level logic of the CTRL pin signal maximum voltage is allowable
leakage current of the switch at 12V is 0.5 mA.
Remote ON/OFF Implementation Circuits
Isolated-Closure Remote ON/OFF Level Control Using TTL Output
Level Control Using Line Voltage
There are two remote control options available, positive logic and negative logic.
a. The Positive logic structure turned on of the DC/DC module when the CTRL pin is at high-level logic and low-level logic is turned
off it.
When TEP 75WI module is turned off at Low-level logic When TEP 75WI module is turned on at High-level logic
b. The Negative logic structure turned on of the DC/DC module when the CTRL pin is at low-level logic and turned off when at high-
level logic.
When TEP 75WI module is turned on at Low-level logic When TEP 75WI module is turned off at High-level logic
