AC-DC power factor correction module offers up to 1512W in a full brick package for high voltage distributed power architectures

Posted : 24 Jan 2023

TDK Corporation (TSE:6762) announces the introduction of the TDK-Lambda brand PF1500B-360 full brick power module, capable of providing up to 1512W. The power supply has a 0.98 power factor and delivers a regulated 360Vdc non-isolated voltage from an AC input. The PF1500B-360 can be used to drive isolated high voltage input DC-DC modules in a distributed power architecture configuration, or loads requiring a high voltage DC input. Applications include semiconductor fabrication, LED lighting and custom power supply solutions using power modules.

With an input of 170 to 265Vac, the PF1500B-360 provides 1512W and 1008W when operated from 85 to 265Vac. The 96.5% efficiency ensures reliable operation with baseplate temperatures of up to +100°C and in ambient temperatures of -40 to +85°C. The module has the industry standard full brick package size, measuring 116.8mm in length, 61mm wide and 12.7mm high for low profile applications.

As standard, the PF1500B-360 provides a 10 - 16V 10mA auxiliary voltage, remote on/off and an inverter good signal. An enable function is available to activate isolated DC-DC converters when the output voltage is greater than 360Vdc to synchronise output rise times. Parallel connection with current sharing of up to three modules is possible for additional output power.

Input and output to baseplate isolation is 2,500Vac. The PF1500B-360 is certified to the IEC/EN/CSA/UL 62368-1 standards and is CE / UKCA marked to the Low Voltage, EMC and RoHS EU Directives and UK regulations. With external circuitry, the PF1500B-360 will meet radiated and conducted emissions and comply with the IEC 61000-4 immunity standards.
