DC Electronic Loads

To truly understand how your power source performs under pressure, you need to test it against real-world conditions. A DC Electronic Load allows you to simulate various types of electrical demand—from steady-state draws to rapid, high-current pulses—with total control and safety.

Telonic’s selection of programmable electronic loads is designed for engineers who need to verify the efficiency, stability, and safety of their power designs. Whether you are discharging a battery to map its capacity or stress-testing a switching power supply, our loads provide the high-speed dynamics and accuracy required for modern power electronics.

Why Choose a Programmable Load?

Multiple Load Modes: Support for CC, CV, CP, and CR modes to replicate any real-world device behaviour.
Dynamic Testing: Simulate rapid “step” changes in load to test the transient response of your power supply.
Precise Measurement: Integrated high-accuracy voltmeters and ammeters eliminate the need for external tools.
Safety Protections: Automatic shut-off for over-power (OPP), over-current (OCP), and over-temperature (OTP).

Core Applications

Battery Testing: Controlled discharge testing to measure capacity, internal resistance, and cycle life.
Power Supply Validation: Testing voltage regulation and efficiency across the full range of output currents.
Solar Panel Characterisation: Sinking current from photovoltaic cells to determine the Maximum Power Point (MPP).
Fuel Cell Research: High-precision sinking for renewable energy development and stack testing.
