Reduce Costs for Cooling and Electricity

The RP5925A regenerative power supply returns up to 95% of absorbed energy back to the grid efficiently, helping lower energy and cooling costs without disrupting grid stability. It automatically redirects excess power during current sinking, requiring no programming. To protect your Device Under Test (DUT), the RP5925A safely synchronizes with the grid by detecting live status, phase voltage, and frequency in real time before initiating power regeneration.

Delivers Versatility of Several Power Supplies in One

The RP5925A power supply features an autoranging output that broadens its power delivery capabilities, allowing a wide variety of voltage and current combinations from a single unit. Unlike traditional supplies with fixed rectangular output profiles that provide full power at only one point, the RP5900 adjusts dynamically across a broad range—essentially offering the versatility of multiple power supplies in one.

Emulate a High-Power Battery from the Front Panel

With its battery emulation feature, the RP5925A allows you to test devices under realistic power conditions—critical for evaluating battery life and identifying early failures. Its bidirectional design and adjustable output impedance make it easy to define battery characteristics such as voltage, capacity, internal resistance, and State of Charge (SOC) directly from the front panel, enabling accurate simulation of both charging and discharging behavior.

Bidirectional Source and Independent Electronic Load

The RP5925A combines a bidirectional power supply and a regenerative electronic load in one unit, capable of continuously sinking up to 100% of its rated current. Its two-quadrant design allows seamless transitions between sourcing and sinking modes, offering flexible and efficient power control without the need for separate equipment.

Generate Voltage and Current Transients

To ensure your DUT stands up to these real-world transients, you must simulate worst-case power transient conditions during testing. The RP5925A provides three functionalities for simulating either voltage or current transients for testing: Step, Constant dwell arbitrary waveforms and List

Multiple Operating Modes

The RP5923A provides voltage priority mode (CV), current priority mode (CC), resistance priority mode (CR), and power priority mode (CP). Additionally, four other complex modes are also available.

Add Power Flexibility to Your Test System

Paralleling multiple power supplies together enhances power flexibility in test systems, but conventional loads often struggle to maintain consistent Constant Voltage (CV) or Constant Current (CC) modes when paralleled, leading to performance issues like poor transient response. The RP5900 Series solves this with built-in paralleling that ensures balanced current sharing and consistent mode operation, supports primary/secondary configuration for unified control of up to 192 kW, and allows up to 16 units to be paralleled. Parallel connection of mixed models with identical voltage rating is only applicable for 6kW and 12kW models with the same firmware version.

Optional rack mounts available: RP5904C (1U) and RP5905C (2U).

RP5900 Series
