General Description
Tracopower new launched THL 3WISM series comprising 16 different models. The THL 3WISM 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.
The internal filter which meets EN55022 Class A without external components makes the converter easy to design in.
They come with remote On/Off and short circuit protection. THL 3WI converter is an excellent solution for data- and
telecom applications and for instrumentation and Industrial electronics.

3W SINGLE & DUAL
Output Over Current Protection To provide protection in a fault (output overload) condition, the unit is equipped with internal current limiting circuitry
and can endure current limiting for an unlimited duration. At the point of current-limit inception, the unit shifts from
voltage control to current control. The unit operates normally once the output current is brought back into its
specified range.
Short Circuitry Protection Continuous and auto-recovery mode.
During short circuit, converter still shut down, The average current during this condition will be very low and the
device will be safe in this condition.
Remote ON/OFF Control The positive logic remote ON/OFF control circuit is included.
Turns the module ON during logic High on the ON/Off pin and turns OFF during logic Low. The ON/OFF input
signal (Von/off) that referenced to GND. If not using the remote on/off feature, please open circuit between on/off
pin and -Vin pin to turn the module on.
The negative logic remote ON/OFF control circuit is included.
Turns the module ON during logic Low on the On/Off pin and turns OFF during logic High. The On/Off pin is an
open collector/drain logic input signal (Von/off) that referenced to GND. If not using the remote on/off feature.
Please short circuit between on/off pin and –Vin pin to turn the module on.

Safety and Installation Instruction Fusing Consideration
Caution: This power module is not internally fused. An input line fuse must always be used.
This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone
operation to an integrated part of sophisticated power architecture. To maximum flexibility, internal fusing is not
included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety
agencies require a normal-blow fuse in 24Vin with maximum rating of 1500mA and in 48Vin with maximum rating of
800mA. Based on the information provided in this data sheet on Inrush energy and maximum dc input current; the
same type of fuse with lower rating can be used. Refer to the fuse manufacturer’s data for further information.
MTBF and Reliability The MTBF of THL 3WISM series of DC/DC converters has been calculated using MIL-HDBK 217F NOTICE2,

THL 3-2411WISM  MTBF = 837,942 Hours
THL 3-2412WISM  MTBF = 846,238 Hours
THL 3-2413WISM  MTBF = 854,847 Hours
THL 3-2415WISM  MTBF = 860,437 Hours
THL 3-2421WISM  MTBF = 836,750 Hours
THL 3-2422WISM  MTBF = 850,051 Hours
THL 3-2423WISM  MTBF = 850,051 Hours
THL 3-4810WISM  MTBF = 839,842 Hours
THL 3-4811WISM  MTBF = 841,468 Hours
THL 3-4812WISM  MTBF = 846,668 Hours
THL 3-4813WISM  MTBF = 852,660 Hours
THL 3-4815WISM  MTBF = 858,516 Hours
THL 3-4821WISM  MTBF = 841,538 Hours
THL 3-4822WISM  MTBF = 851,499 Hours
