Datasheet

Tumbler Technologies + TRUMPower has launched a new addition to its AC/DC switching power supply line-up with the Class I/II TMC300 series, which has BF rated outputs.

Specifically designed for medical applications, it is capable of delivering 300W of continuous output power at 10 CFM forced air or 200W at convection cooling. Standard form factor is an open frame PCB in a low profile 3” (L) by 6” (W) by 1.38” (H) package. L-bracket form factor and enclosed frame with cooling fan versions are also available. It has an active efficiency of 87% and features a power factor of 0.98 typical with active PFC. Power consumption in standby mode is less than 1W at standby power 5V/100mA.

Features include Power Fail Detection (PFD) and remote inhibit which will allow the designer to pack in additional safeguards to protect the patient and the operator. Remote sensing capability is standard across all models in the TMC300 series which can be used to regulate the voltage on the device side rather than its own output terminals to compensate for the voltage drop caused by the resistance of load leads, relays, and connectors.

The BF rated power supply provides 2 MOPP between input and output, and 1 MOPP between input and ground. The TMC300 series can withstand voltage of 4,000 VAC from input to output, 1,500 VAC from input to ground, and 1,500 VAC from output to ground. The series includes 7 standard models of single 12V to 48V power supplies each with an actual earth leakage current measuring 143µA at 264VAC, 63 Hz. Output voltage is factory preset specifically to meet the user’s request.

Operating at a 90 to 264 VAC universal input, the series has 12V @ 1A or 5V @ 2A maximum standby power to choose from, along with fan power of 12V @ 1A maximum (isolated). The unit is equipped with overvoltage protection and overcurrent protections. It operates at 0°C to +70°C ambient with derating required from 100% at +50°C linearly to 50% at +70°C. Its 250,000 hours-minimum MTBF at full load at 25°C ambient per MIL-HDBK-217F proves to be highly reliable. Operation altitude is up to 5000 meters.

The TMC300 series complies with RoHS requirements and EMC standards that include EN55011/55022 & 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. The series is approved by UL, cUL and TUV to 3^rd edition UL/IEC/EN 60601-1, ANSI/AAMI ES 60601-1:2005, CSA C22.2 No. 60601-1:08 medical standards and to 2^nd edition UL/IEC/EN 60950-1, CSA C22.2 No. 60950-1 ITE standards.

The TMC300 series are competitively priced in OEM quantity, with delivery from stock to 8 weeks ARO.
