Amrel PEL2.5K-1

The Amrel PEL2.5K-1 is a 2500W programmable DC electronic load engineered for power supply evaluation, battery testing, and DC source characterization. Operating across constant current (CC), constant voltage (CV), constant resistance (CR), and constant power (CP) modes, this unit delivers flexible load simulation for bench and rack-mount installations. The PLA series architecture combines compact footprint with high power density, supporting continuous operation in standalone and integrated test systems.

– Technical Specifications

• Power Rating: 2500W maximum
• Input Voltage: 110/230 VAC
• Operating Modes: Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR), Constant Power (CP)
• Range Selection: Three overlapping ranges (low, medium, high) for voltage, current, resistance, and power with auto-range and manual-range control
• Ultra-low Voltage Operation: Operates at levels approaching 0.1V with full rated current dissipation below 1% of maximum rated voltage
• Transient Capability: Built-in pulse generator supporting continuous, pulsed, and toggled transient modes with programmable pulse amplitude, width, and cycle via local and remote control

– Key Features

• Seven programmable protection modes: Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Current Protection (OCP), Under Current Protection (UCP), Over Power Protection (OPP), and Under Power Protection (UPP)
• Individual FET protection isolating failures to prevent cascading damage and reduce Mean Time To Repair (MTTR)
• Closed-case calibration accessible from the front panel, eliminating factory service requirements

– Typical Applications

• Power supply evaluation and validation
• Battery discharge testing and characterization
• DC equipment and control circuit assessment
• Burn-in and reliability testing
• System-level power source verification

– Compatibility & Integration

The PEL2.5K-1 integrates into both standalone test benches and multi-unit systems, with programmable control enabling automated test sequences and remote operation.
