The Lambda / TDK / EMI LPT7202FM is a triple-output DC power supply engineered for laboratory and industrial applications requiring independent voltage and current regulation. Each output operates in constant voltage (CV) and constant current (CC) modes with automatic crossover, delivering three isolated supplies from a single 103 VA unit. Coarse and fine voltage controls with separate meters enable precise setpoint adjustment and real-time monitoring across all ranges.
Technical Specifications

• Ripple and noise: 500 µV RMS; 1.5 mV peak-to-peak
– Key Features
• Voltage-regulated outputs for both line and load variations
• Current-regulated outputs with electronic current-limiting circuit, settable to 105% of rated current
• Remote sensing provision eliminates power lead voltage drops for tighter regulation
• Negative or positive terminal grounding, or floating operation
• Series/parallel output capability—two LPT-7202-FM units in series extend voltage to 300 V between terminals and chassis ground
• Automatic thermal protection with self-reset upon temperature normalization
• Frequency operation: 47–440 Hz (derate 10% for 47–53 Hz; consult factory for 63–440 Hz)
– Typical Applications
Component testing, circuit development, prototype power distribution, industrial equipment commissioning, and laboratory benchwork requiring multiple independent supplies.
