Our Heavy-Duty, Reliable, and Accurate vs. Copycats' Lightweight, Cheaply-constructed, and Poorly-performing, Your Choice[edit]

A linear power supply design applies the AC voltage to a power transformer to raise or lower the voltage before being applied to the regulator circuitry. Whereas a switch-mode power supply converts the AC power directly into a DC voltage without a transformer, and this DC voltage is then converted into a high frequency AC signal, which is used in the regulator circuit to produce the desired voltage and current. The linear power supply is quiet, stable, durable and heavy-duty with little noise, ripple, delay, and EMI, the switching type is just the opposite.

The Tekpower TP3005T variable DC power supply is a compact linear type instrument that is suitable for both Lab and industrial use. This digital DC power supply has maximum output voltage of up to 30 volts and current up to 5 amps. It comes with rotary switches for setting up the voltage and current. With its reliability and versatility, it's an invaluable and indispensable tool for testing, science project and etc., ideal for labs, research institutes, R & D facilities.
