MasTec Premier Supplier

Accel Instruments Products

Accel Instruments designs, develops, manufactures and markets electronic instruments for the specialized needs of electronics bench testing and research and development. We specialize in power electronic test and measurement such as voltage regulators, battery chargers, amplifiers, and more. We solve the needs of the customer through offering innovative products that ease their test and measurement challenges.

Focus On Power Electronics
Our instruments focus on power electronic devices and systems. These devices include linear regulator or LDO, switching mode power supply (SMPS), battery chargers, and more. We make instruments for power electronic device test and measurement.

TS100 precision electronic load link

Designed for testing voltage regulators such as LDOs and switching-mode power supply (SMPS). It provides a constant current load for testing voltage regulators. It is ideal for testing linear regulators (LDO), switching DC-to-DC converters, power supply modules, wall adapters, and more.

TS200 Modulated Power Supply link

A unique instrument for many test and measurement applications such as LDO PSRR measurement, battery simulator, op amp CMRR measurement, function generator amplifier, transient response test, four-quadrant power supply, lab power amplifier and more.

TS300/Ultra-Low-Noise-Power-Supply link

Ultra low noise: 8nV/rt-Hz
Special construction immune to environmental noise
Spurious free (No 60Hz/50Hz hum noise)
90W output power (0-30V and 0-3A)
Current limit control
4-wire remote voltage sense
