Each voltage range is equipped with finely adjustable step settings, featuring a resistance accuracy of ±3% and precise load regulation, thereby meeting various DC power supply testing requirements.

Excellent heat dissipation capabilities and supports prolonged continuous operation.

Equipped with a front-to-back forced air cooling system, featuring a dedicated 12038 fan, with noise levels ≤90 dB at a distance of 1 meter; supports uninterrupted online continuous operation 24/7, and incorporates built-in overheat alarm, overvoltage protection, and emergency stop function, ensuring stable and reliable operation.

Easy to operate, offers both protection and portability.

Equipped with a button-and-circuit breaker control system, the digital display provides real-time visualization of power, current, and voltage values, offering a clear overview of the operating status; features an IP20 indoor protection rating and a 28kg unit weight, complemented by casters for a portable design that facilitates easy mobility; utilizes threaded terminal blocks for wiring, ensuring secure and reliable connections.

The parameter configuration is highly refined, with high precision in segmented adjustment.

Different voltage levels feature independent adjustable ranges: DC48/52V covers multiple ranges from 1–100A; DC24V offers fine-grained sub-ranges up to 50A; and DC12V allows for minimum adjustment of 0.25A with a step accuracy of 1A, enabling stepwise load testing.

Factory testing of DC power supply products

Suitable for manufacturers of switching power supplies, DC-DC modules, lithium-ion battery chargers, and DC regulated power supplies; designed to perform full-load, half-load, and step-load aging tests during the factory testing phase to verify the output stability of the power supply.

Performance Testing of Storage Batteries and Power Batteries

Designed for discharge testing of 12V/24V/48V lead-acid batteries and lithium-ion battery packs; it enables constant-current discharge testing across various current settings to measure battery capacity, voltage drop, and load-carrying capability.

DC System Acceptance Test for Telecommunications Equipment Rooms

Load-bearing test for the DC48V power supply system of communication base stations and the UPS DC power panel, simulating actual load conditions to verify the load-carrying capacity and voltage drop characteristics of the switching power supply and distribution cabinet.

Laboratory R&D and Commissioning Scenario

Laboratory for the research and development of automotive low-voltage electrical components, on-board DC power supplies, and new energy low-voltage components, designed for DC power supply equipment load simulation and aging durability testing.

Q1: Can this load cabinet support multiple voltages simultaneously?

A: It does not support simultaneous multi-voltage output; the device operates in switching mode, allowing only one voltage level (DC12V/24V/48V/52V) to be selected individually for load testing; multiple voltages cannot be connected simultaneously.

Q2: Can the equipment operate continuously at full load for 24 hours?

A: Yes, this unit is designed for a 7×24-hour online continuous operation mode; it features a robust forced-air cooling system that enables long-term operation under full-load conditions, as well as overheat protection that will automatically trigger an alarm in case of abnormal temperature.

Q3: Is the gear adjustment system continuously variable or stepwise?

A: This is a stepwise gear adjustment system; it is not continuously adjustable. The equipment switches the load size based on fixed current range combinations, with a step resolution of 1A; current adjustment is achieved by selecting different combination sets of gears, and arbitrary current values cannot be set.

Q4: What are the specifications of the equipment's auxiliary power supply? Can it be used without AC220V?

A: The equipment's auxiliary power supply is based on standard AC220V,50/60Hz mains electricity; both the overall system control and the cooling fan require AC220V power supply. Without a mains power input, the equipment cannot start, and cannot operate independently without alternating current (AC).
