The series offers a low earth leakage current of less than 200 µA at 264 VAC and 63 Hz. The peak power for 10 seconds is as high as 270 W. With an active efficiency of up to 91%, these units are compliant with the CEC and Energy Star Level V standards.

Offering up to 135 W of continuous output power, the TMP135 series provides a flexible range of output voltages including 12 V, 13 V, 14-16 V, 18-19 V, 20-21 V, 24-25 V, 28-29 V, 30-32 V, 36-38 V, or 46-50 V. The TMP135 models come equipped with the IEC 320/C14 AC inlet for the Class I models and the IEC 320/C18 AC inlet for the Class II models. Measuring 6.73 (L) x 2.83 (W) x 1.65 (H) inch, the fanless units come with a power-on LED indicator and a 4-pin circular DIN output connector. TRUMPower also offers many other connector options and can accommodate special requirements.

The TMP135 units are protected against overvoltage and overcurrent conditions and deliver a reliable 150,000 hours-minimum MTBF at full load at 25°C ambient per MIL-HDBK-217F. They can also withstand voltage of 4000 VAC from input to output, 1500 VAC from input to ground, and 500 VAC from output to ground.

With an active power factor of 0.98, the TMP135 series operates at a 90 to 264 VAC universal input. Inrush current is 80 A @ 115 VAC or 160 A @ 230 VAC, at 25°C cold start and the units also come with soft start function. These models can operate at full load in temperatures ranging from 0°C to +40°C with derating required from 100% at +40°C linearly to 50% at +60°C.

The units comply with the RoHS requirements and EMC standards that include IEC60601-1-2, EN55011/EN55022 & FCC class B, EN61000-3-2, EN61000-3-3, EN61000-4-2, EN61000-4-3, EN61000-4-4, EN61000-4-5, EN61000-4-6, EN61000-4-8, and EN61000-4-11.

Availability and Pricing

The TMP135 series is priced at $75/ea in OEM quantity. Units are available from 8 to 12 weeks ARO.
