DC/DC Converter THL 25 Series, 25 Watt High power density 25W converter Ultra compact design: 1.0 x 1.0 x 0.4 Shielded metal case with isolated baseplate Wide 2:1 input voltage ranges Very high efficiency up to 90% UL 62368-1 IEC 62368-1 Output voltage adjustable The THL 25 series is a generation of DC-DC converter modules with high pow- Remote On/Off control er density. The product achieves 25 Watt output power and comes in a metal case with small dimensions of only 1.0x 1.0x 0.4. All models have a wide 2:1 Operating temp. range 40C to +80C input voltage range and precisely regulated output voltages. High efficiency of and up to +85C with heat-sink up to 90% makes this product very reliable and applicable in temperature I/O isolation voltage 1500 VDC ranges of up to +80C or up to +85C with optional mounted heat sink. Typical applications are in mobile equipments, instrumentation, distributed power ar- 3-year product warranty chitectures in communication and industrial electronics and everywhere where space on the PCB is critical Models Order Code Input Voltage Output 1 Output 2 Efficiency Range Vnom Imax Vnom Imax typ.
