The GI-SI Series pulsed AC current generators are engineered to deliver stable and precise current output for demanding testing applications. With current ranges from 900A to 40kA and power capability up to 300kVA per unit, the systems provide reliable sinusoidal and user-defined current waveforms across flexible operating ranges.
Designed for ease of operation, the GI-SI Series supports remote interfaces, analogue amplification, and digital input/output control, making it suitable for laboratory, R&D, and production environments.
An integrated sequencer and timer enable accurate circuit breaker and switch testing, while continuous current operation is supported up to one-third of the maximum current rating. These capabilities make the system ideal for testing circuit breakers, thermal and magnetic evaluation of contacts, coils, transformers, and related high-current applications
Designed for pulsed current applications including circuit breaker testing, delivering high power, wide current ranges from 900A to 40kA Upto 3 output Range
Generates sinusoidal and arbitrary current waveforms with up to three selectable current ranges to support a wide variety of testing requirements as per IEC 60947-2 .
Integrated timer and sequencer provide accurate trip-time measurement down to 1ms, making it suitable for circuit breaker validation.
Remote control (RS232/RS485, optional USB/LAN/fiber), analog inputs, and digital I/Os for lab and production automation
The GI-SI Series is designed for circuit breaker and switch testing, R&D validation, current amplification, automated production testing, custom waveform generation, and instrument calibration. Its high-current capability enables accurate simulation of real-world operating conditions for a wide range of electrical test applications.
The GI-SI Series features a sealed, splash-resistant membrane keypad and a large backlit LCD display for clear parameter visualization and system status monitoring. Front-panel programming allows test sequences to be configured, stored, and locked, while trip current and pulse duration can be measured with millisecond-level resolution.
Optional GI-Software enables remote control of the GI-SI IS Series through available communication interfaces. Test sequences can be created, edited, stored, and recalled, simplifying engineering development, laboratory testing, and production validation processes.
The GI-SI Series is a pulsed AC current source designed to generate precisely controlled AC current waveforms, including pulsed and dynamic current profiles, for specialized testing applications.
A pulsed AC current source delivers programmable AC current pulses with controlled amplitude, timing, and waveform shape. Unlike voltage sources, it ensures the required current flows through the DUT, regardless of impedance changes.
AC power source → Controls voltage and frequency
AC current source → Controls current magnitude and waveform
The GIIS Series is used when current accuracy and repeatability are more important than voltage control.
The GI-SI Series is designed for:
Highcurrent pulsed testing
Immunity and stress testing
Component and system validation
Applications where currentdriven behavior must be evaluated
Yes. The GI-SI Series supports remote control and automation, allowing integration into automated test systems and softwaredriven test sequences.
The GI-SI Series can be integrated into coordinated test setups, enabling synchronized operation with other instruments as part of a complete test system.
