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
• Remote sensing terminals for external voltage monitoring
– 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.
