DESCRIPTION
The GS5T24-5D15 is a 5W DC-DC converter de-
signed to provide three isolated outputs: 5V/200mA
and a dual ±15V/±125mA.
The module operates from a 24V input source and
offers 2500V_DC isolation voltage. A high level
TTL/CMOS compatible input will enable the unit; a
low input will inhibit it.
