Bench DC Power Supply 0-30V 5A
The STP3005 is a regulated switching bench supply delivering zero to thirty volts and zero to five amps for laboratory, production-line and repair work. A three-digit LED display reads voltage to 0.1 V and current to 0.01 A. Automatic crossover between constant-voltage and constant-current modes keeps the output stable across varying loads. Alligator-clip leads and a 110 V AC cord are included for immediate bench use.
Adjustable 0-30 V / 0-5 A Output Range
The single specification that determines fit is the continuously adjustable zero-to-thirty-volt and zero-to-five-amp output envelope. If the device under test requires more than thirty volts or more than five amps this unit cannot supply it. Within those limits the supply maintains regulation rates of 0.03 % plus 1 mV for voltage and 0.2 % plus 5 mA for current. Ripple and noise stay at or below 3 mA RMS on the current channel.
Quiet Fan Cooling and 85 % Efficiency
An internal fan runs quietly while keeping component temperatures in check during extended sessions at full load. Overall efficiency reaches 85 %, so waste heat remains moderate even when delivering the full five amps. Protection circuits cover over-voltage, over-current, short-circuit and thermal events, allowing the supply to recover within 300 microseconds after a fifty-percent load step. The unit operates reliably from zero to forty degrees Celsius.

Questions about this item
What does the 0–30 V / 0–5 A range mean when I’m powering a real circuit?
You can set any voltage from 0 to 30 V and any current limit from 0 to 5 A; the supply automatically switches between constant-voltage and constant-current modes so the output never exceeds your chosen limits.
The spec says 110 VAC input — what does that cap in practice?
The unit runs on 110 VAC ±10 % at 60 Hz, so it plugs straight into a standard North American outlet; other mains voltages require an external step-down transformer.
What does the bench supply need to sit securely on my bench?
It measures 11.8 × 5 × 7.2 inches and weighs 2.87 pounds, so a flat, stable surface with a few inches of clearance for the built-in fan is all that’s required.
