R-78HBxx-0.5/W Series Switching Regulators (non-isolated)
The R-78HBxx/W series high efficiency, high input voltage switching regulators are ideally suited to replace 78xx linear regulators. The efficiency of up to 93% means that very little energy is wasted as heat so there is no need for any heat sinks with their additional space and mounting costs. A wide input voltage range allows the full stored energy utilization of standard 12, 24 and 36V batteries as well as COB LED drivers. No external components are required to make a complete regulated, short-circuit protected supply. A built-in protection diode allows high capacitive loads. Typical applications include Auxiliary fan CV power supplies powered from CC LED drivers, industrial, aerospace and battery powered applications.

AC/DC-Power Supplies provide DC-Voltage to generations of electronic designs. Since the introduction of the EuP-Directive (energy saving products) in January 2010 the focus is on high efficiency. Particularly electronic devices with a standby- function require a small power supply to meet this directive. The modules of our AC-family provide 1 to 960 Watts power. They feature a high packing density, low no-load current and have an MTBF guaranteeing 40 years of continuous operation.
