100W Single Output
Remote ON/OFF Control
The Remote ON/OFF 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 -V
in
. 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 ON/OFF 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 ON/OFF pin is at high-level logic and low-level logic is
turned off it.
When TEP 100 module is turned off at Low-level logic When TEP 100 module is turned on at High-level logic
b. The Negative logic structure turned on of the DC/DC module when the ON/OFF pin is at low-level logic and turned off when
at high-level logic. To order TEP 75WI with negative remote on/off logic please add –N on the order code.
When TEP 100 module is turned on at Low-level logic When TEP 100 module is turned off at High-level logic
