General Description

Tracopower new launched THL 3WI series comprising 16 different models. The THL 3WI has wide input voltage

ranges of 9 – 36Vdc and 18 – 75Vdc and is available in output voltages of 3.3Vdc, 5.0Vdc, 12Vdc, 15Vdc, 24Vdc,

±5Vdc, ±12Vdc and ±15Vdc.

Pin compatible with the TEL 2 series, the THL 3WI offers a power rating up to 3W and a typical full-load efficiency of

80%, continuous short circuit, remote on/off control, EN55022 Class A conducted noise compliance minimize

design-in time, cost and eliminate the need for external filtering.

The THL 3WI series is an excellent selection for data communication equipment, mobile battery driven equipment,

distributed power system, telecommunication equipment, mixed analog/digital subsystem, process/machine control

equipment, computer peripheral equipment and industrial robot system.
