DRB 3 PHASE SERIES
The DIN-Rail power supplies in the DRB series are part of TDK-Lambda's industrial heritage. They can be used in many applications, ranging from conventional switch cabinets and decentralised machinery and systems, to information and communications technology solutions. The series covers the popular output voltages of 12, 24, 48 and 72 volts, and users can choose between screw and push-in terminal blocks. All seven major electrical safety standards are covered, enabling global market access. The DRB's high operating efficiencies, conservative thermal design and redundant overvoltage protection measures provide maximum system up-time. Product reliability is also supported by a reduced component count and TDK-Lambda's stringent testing requirements. Overall the DRB 3 phase series offer an excellent balance between functionality and price.
Powerful with capacitive loads
Starting into a capacitive load poses a challenge for many power supplies. Thanks to comprehensive peak power capability of 150 percent, the DRB series can reliably operate under these conditions.
Nuisance circuit breakertripping? Not a problem!
The input inrush current of the power supplies lasts less than 2ms. This, combined with a very low energy content of the initial current drawn, false or nuisance tripping of the line protection circuitry is avoided.
Distributing load current, enhancing reliability
To provide additional power, DRB models of the same voltage and current can be connected in parallel. Using the front panel dip-switch, the DRBs can be easily configured from single to parallel operation. The load current is then shared between the power supplies, reducing the thermal stress on the electrolytic capacitors and enhancing field longevity.
Supporting system controls
The availability of the output voltage can be remotely determined using the DC-OK relay contact. To avoid false notifications, voltage drops lasting less than 100ms are not reported. The highly responsive inhibit contact enables the DRB power supplies to be turned on and off in an effective manner.
