Three-phase DIN rail-mounted power supplies from TDK-Lambda

TDK-Lambda is a Japanese manufacturer of industrial converters. Recently, the TME catalogue has expanded to include 3-phase DIN rail-mounted power supplies from this supplier. Those are products of the popular DRB series, which has previously been marketed as a group of devices designed for 1-phase systems.

The converters are available in three output voltage versions: 12 V, 24 V and 48 V DC, and in 2 power rating versions: 120 W and 240 W. All the models feature overcurrent OCP, overvoltage OVP and overtemperature OTP protection. In addition, it should be noted that the converters include versions with screw terminals or push-in terminals.

The DRB series devices offer increased power operation (up to 120% of the rated value) for 2 seconds. As a result, they can be switched-on without tripping the surge protection when powering high-capacitance loads. In addition, the DRB series products can operate independently or in parallel, which makes it easy to increase the total power supply capacity.

The TDK-Lambda power supplies presented here boast efficiency of up to 94% (more info).
