Product Review: The Hantek Programmable DC Power Supply, Model PPS2116A

The newest addition to Circuit Specialists’ line of programmable DC power supplies is the Hantek model PPS2116A. This power supply may be run manually as a standard benchtop power supply or may be controlled and monitored by an external computer system.

The Hantek PPS2116A may be run in constant voltage or constant current mode. The unit features completely isolated outputs that may be connected in series or parallel configurations to other isolated power supplies for higher current and voltage operation.

The Hantek PPS2116A is capable of operation from 0-30 volts with up to 5 Amps output current. It offers programmable or adjustable current limiting and constant current operation with resolution as fine as 10mV for voltage and 1mA for current.

The desired voltage and current levels may be stored in the unit’s on-board, non-volatile memory, for easy retrieval of previously used settings. You may store up to five sets of voltage and current settings. The unit also features a lockout button that prevents any inadvertent changes to the operational settings. Convenient LED status indicators show at a glance the operating mode of the unit at all times (i.e. Constant Current (CC), Constant voltage (CV), or Overcurrent Protect (OCP) operation).

The power supply is supplied with the necessary drivers and computer control/monitoring software for Windows-compatible computers. It features a standard USB interface port and does not require any additional interface converters. The software offers real-time monitoring and control of all operations using an easy-to-use graphical user interface.

The Circuit Specialists Hantek PPS2116A programmable DC power supply is a powerful yet affordable power supply with features that rival more expensive units. It is well-suited for use in design and development labs, test and repair facilities, and manufacturing environments.
