Lambda / TDK / EMI LP533

The Lambda/TDK LP533-FM is a regulated DC power supply delivering 0-60 VDC at 0-2.4 ADC for laboratory and production environments requiring stable, filtered power. This metered benchtop/rack-mount unit combines constant voltage and constant current operation with front-panel controls and integrated EMI filtering to support sensitive electronic testing and power delivery applications.

Key Features

• Constant voltage/constant current dual-mode operation


• Coarse and fine voltage adjustment controls on front panel


• Single current adjustment control on front panel


• Integrated voltmeter and ammeter (FM metered models)


• Remote sensing provision to eliminate lead resistance effects on DC regulation


• Convection-cooled design - no blowers or external heat sinks required


• Five-way binding posts for DC output connections (+, −, GND)


• Detachable 5-foot, 3-wire line cord with heavy-duty rear terminal block connection

Typical Applications Laboratory power delivery, production test stands, sensitive equipment development, and environments requiring clean, regulated DC with automatic current limiting and thermal protection.

Compatibility & Integration Designed for both benchtop and rack-mount configurations. Compatible with standard test environments using external meters via test jacks (non-metered models) or built-in panel meters (FM models). Remote sensing capability enables compensation for voltage drop across distribution leads.
