Adjustable DC Power Supply

The Tekpower TP3005DC is a single-output variable DC power supply delivering zero to 30 volts and zero to 5 amps. Digital computer control sets voltage and current with high resolution for low ripple output. It suits bench testing, prototype powering and general lab work where precise regulation matters. The unit accepts 110 volt or 220 volt AC input at 50 hertz or 60 hertz.

Thermals Noise and Power Draw

The supply operates from minus 10 degrees Celsius up to 40 degrees Celsius in ambient humidity up to 90 percent. Voltage stability is rated at 0.005 percent plus 1 millivolt, indicating tight regulation under load. No fan noise figure or power consumption value is provided in the specifications. Surge protection at the output helps prevent transients when the unit is switched off.

Build Integration Needs

A detachable AC power cord is included for immediate mains connection. Selectable 110 volt or 220 volt input allows use in different regions without an external adapter. The lightweight chassis and back-lit LCD display simplify bench placement and reading. Buyers who need multiple independent outputs or higher current capacity will require additional units.

Questions about this item

How do I set the correct input voltage before plugging in the TP3005DC?

The default input is 110 V; slide the rear selector to 220 V if your mains supply is 220 V before connecting the included AC cord.

What maintenance does the TP3005DC require over time?

Keep the ventilation slots clear of dust and verify the output voltage against a calibrated meter periodically; no user-serviceable parts are described.

At what temperature does the TP3005DC reach its operating limit during sustained use?

The rated working range tops out at 40 °C; above that the supply may shut down or drift out of its 0.005 % + 1 mV stability spec.
