ActionPower feels proud to announce the release of our new PCL Series DC Electronic Load, a next-generation solution designed for high-precision and high-speed testing of DC power sources, batteries, and energy storage systems. The PCL series combines fast transient response, accurate measurement, and compact modular design to meet the evolving demands of power electronics and renewable energy testing. With its versatile operation modes—including constant current, constant voltage, constant resistance, constant power, and dynamic pulse—the PCL series can simulate a wide range of real-world load conditions.
At the heart of the PCL series is a high-speed current control loop capable of achieving transient response times down to 20 µs. This enables the load to accurately simulate rapid load changes, an essential requirement for modern DC/DC converters, automotive power electronics, and renewable energy systems.
The system employs independent measurement channels for current and voltage, ensuring high accuracy and stability across a wide operating range. The modular chassis design supports scalable power configurations, allowing multiple load modules to be parallelled for higher capacity while maintaining synchronized control.
Fast and precise response for capturing dynamic performance of power supplies and converters.
High measurement accuracy with independent current and voltage channels.
Compact, modular form factor optimized for both laboratory and production test environments.
Broad application coverage, from switch-mode power supplies and DC/DC converters to batteries, fuel cells, and renewable energy systems.
The PCL series supports a complete set of load operation modes to replicate different real-world load conditions:
Constant Current (CC): Maintains programmed current independent of source voltage.
Constant Voltage (CV): Forces the input voltage to a programmed level.
Constant Resistance (CR): Simulates purely resistive loads with programmable slope.
Constant Power (CP): Maintains a programmed power draw across varying voltage.
Dynamic & Pulse Modes: High-speed switching between load levels at up to 20 kHz.
Battery Discharge Test: Programmable cutoff conditions for capacity measurement.
Fast Transient Response: <20 µs response enables accurate ripple and stability testing.
Wide Dynamic Range: High resolution across current ranges for small-signal to high-power testing.
High Power Density: Compact form factor suitable for rack integration.
Precision Measurement: Built-in A/D converters with high sampling accuracy for voltage, current, and power capture.
Safety & Protection: Over-current, over-voltage, over-power, and reverse polarity protections ensure DUT and operator safety.
The PCL series is widely applicable in:
Switch-Mode Power Supply (SMPS) Verification – Evaluating transient response, startup behaviour, and stability.
DC/DC Converter Testing – Characterizing efficiency and control loop response under dynamic load steps.
Battery & Energy Storage Systems – Performing charge/discharge characterization, capacity measurement, and cycle life testing.
Fuel Cell Evaluation – Controlled loading for polarization curves and efficiency analysis.
Automotive & Renewable Applications – Testing on-board chargers, solar inverters, and microgrid components.
