The KUB48 Series; High-Density, Non-Isolated Converters for Motor Drives

Relec Electronics are pleased to announce the general availability of the KUB48 Series, ultra high density non-isolated DC-DC Converters. The KUB48 Series are ideally suited to robotic, home automation and general logistics applications where the primary source is a battery.

Housed in an industry standard quarter brick package, and with an efficiency of 97%, the KUB48 Series are the ideal DC-DC Converter solution where regulated 12V or 24V rails up to 10 Amps are required from unregulated battery sources.

The KUB48 series was originally developed for the logistics robot market where either 12V or 24V regulated rails are required to power the drive train, and also provide full output short circuit, over-current, and input under-voltage protection, thus ensuring that no damage can come to either the batteries or the motors.

Key features and benefits of the KUB48 Series are:
