Circuit Specialists 18 Volt, 2.0 Amp DC Power Supply

The CSI1802X is a fully regulated benchtop linear power supply with adjustable current limiting.

Our linear, regulated DC bench power supply provides accurate, stable DC power up to 18 volts and 2.0 amps. The front mounted voltage and current control knobs help the user accurately dial in the desired voltage and current output while the easy to read LCD displays the output. DC power is available via a pair of front mounted terminals that accept banana plugs. High quality SMT PC boards are used and overload protection is present for reliable performance and long life. Output devices are mounted on a large, rear mounted heat sink for thermal stability. High quality, easy portability and low cost make this unit ideal for test benches, laboratories, schools and repair facilities. This 2.0 amp bench power supply provides an economical solution when a higher priced bench top power supply is not required.

Please Note: This power supply uses standard 110-120 volt, 60 Hz AC power and is supplied with a grounded power cable compatible with 110-120 volt power outlets as used in the United States. It is NOT compatible with 220-240 volt, 50 Hz power systems used in other countries unless a proper power adapter/converter is used (not included).

Due to safety concerns, Circuit Specialists does not stock power adapters or converters for power supplies at this time.
