Programmable power supplies are digitally controlled power sources that provide accurate and adjustable levels of voltage, current, and frequency. They include a processor, voltage/current programming circuits, current shunt, and voltage/current read-back circuits

Power supplies are devices that produce AC or DC power.  This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters

DC power supplies accept an input power and output the desired form of DC power. Common types of DC power supplies include linear power supplies, switching power supplies, DC-DC converters, and silicon controlled rectifier (SCR) type power supplies

Three phase uninterruptible power supplies (UPS) are devices that operate in conjunction with existing electrical systems to provide power conditioning, back-up protection and distribution for electronic equipment loads

Programmable logic controllers (PLCs) are the control hubs for a wide variety of automated systems and processes. They use a wide variety of inputs and outputs and provide network capability

Programmable automation controller (PAC) modules are add-on devices that perform a specific control function in PAC systems

Programmable automation controller (PAC) systems consist of PAC modules, each of which performs a specific function. PAC systems are used in motion control, machine control, machine vision, and other industrial control applications

High voltage power supplies use linear technology to provide one or more DC outputs at voltage levels of hundreds or thousands of volts

Programmable automation controllers (PAC) are compact industrial controllers used in applications such as data acquisition and control, machine vision control, and process control. PACs are functionally similar to programmable logic controllers (PLC), but provide the advanced software features of personal computers (PC

Programmable logic devices (PLD) are designed with configurable logic and flip-flops linked together with programmable interconnect. PLDs provide specific functions, including device-to-device interfacing, data communication, signal processing, data display, timing and control operations, and almost every other function a system must perform

LCD and LED programmable switches contain an integrated liquid crystal display (LCD) or light emitting diodes (LED) that show text and graphics. They can be programmed to perform specific functions and provide choices for the selected operation

KVA meters measure the apparent power of AC devices in kilovolt-amperes (KVA). Apparent power is the combination of a circuit’s true power and reactive power

AC power sources provide alternating power and typically have adjustable output values for the testing of component response at various voltage, current and frequency levels

Oscillators are devices that are used to generate repetitive signals. They produce output signals without an input signal. There are two major types of electronic oscillators: harmonic oscillators and relaxation oscillators. Harmonic oscillators produce sine wave outputs. Relaxation oscillators produce non-sine wave outputs such as square wave, rectangular wave, and sawtooth outputs.

Condition monitoring and machine maintenance services monitor the condition of critical machines, battery banks, power supplies, processes and rotary equipment. They also perform predictive maintenance (PdM) and/or preventive maintenance
