Models with Single Output
The TXH series is a family of power supplies in metal enclosure, designed for a wide
range of cost critical applications. The very high efficiency of up to 93% admits
of a compact design with free air convection coouling for the 120 and 240 Watt
models. The units are equiped with screw terminal blocks and are easy to install in
any equipment.
These power supplies have universal input and comply with European EMC stan-
dards and the Low Voltage Directive (LVD).
* 36 VDC output voltage models on request.
