Accurately tests output power, load capacity and other performance indicators of various diesel generator sets, UPS and other equipment, as well as electrical parameter measurement. Important test data can be displayed intuitively and saved automatically. The matched analysis management software records various parameter changes throughout the test and automatically generates test reports.
Product Features
- Equipped with USB interface and dedicated data USB flash drive. It can record high-speed collected voltage, current and transient voltage waveforms during discharge and store data into the USB drive for import to PC. PC management software analyzes battery discharge process and generates corresponding data reports.
- Large touch screen display with touch operation for convenience and intuition; all data shown on one screen.
- Single unit continuously adjustable power from 0~100kW; higher power available via parallel operation.
- Three-phase current adjustable between 0~160A; the unit can operate under unbalanced three-phase load conditions.
- Dual AC & DC load function: automatically identifies AC and DC voltages. Works as both AC load and DC load, meeting discharge test requirements for UPS battery packs.
- Load duration configurable as required, continuously adjustable from 0~99 hours in minute increments.
- Controlled by intelligent ARM microcontroller with Chinese LCD display.
- Supports setting different current, stop time, discharge power and voltage thresholds (both upper and lower limits configurable).
- Equipped with E-STOP emergency stop switch.
- Automatically stops discharge upon excessive three-phase voltage.
- Automatically stops discharge when three-phase voltage is too low.
- Built-in overcurrent and short-circuit protection.
- Triggers alarm and automatically trips load to cut off power if any cooling fan opens circuit or fails.
- Main power-consuming components adopt PTC ceramic resistors, no red-hot phenomenon to avoid overheating and fire hazards.

FAQ | Intelligent AC Load Bank Tester
Q1: What is an Intelligent AC Load Bank Tester used for?
A1: It simulates real AC loads to test diesel generators, UPS and power supply equipment. It verifies output power, load performance and electrical parameters for commissioning, acceptance and routine maintenance.
Q2: Does this unit support both AC and DC discharge testing?
A2: Yes. It can automatically identify AC & DC voltages, working as either AC load or DC load, suitable for discharge tests of UPS battery packs.
Q3: What is the adjustable power range of a single unit? Can units run in parallel?
A3: Single unit power ranges 0~100kW continuously adjustable. Multiple units can be paralleled to achieve higher total load capacity.
Q4: Can the tester work under unbalanced three-phase load conditions?
A4: Yes. Three-phase current can be set freely within 0~160A, and stable operation is supported under three-phase unbalanced working conditions.
Q5: How are test data and waveforms saved?
A5: Equipped with USB interface. Test voltage, current and transient waveforms can be stored to USB flash drive. PC software analyzes data and auto-generates test reports.
Q6: What safety protection functions are built in?
A6: It features E-STOP emergency stop, overvoltage/undervoltage shutdown, overcurrent & short-circuit protection, and fan fault alarm with automatic power cut-off.
Q7: Why adopt PTC ceramic resistive load?
A7: Main load components use PTC ceramic resistors without red-hot phenomenon, effectively lowering risks of overheating and fire for safer field testing.
Q8: Can I set custom test duration and voltage thresholds?
A8: Absolutely. Load time is adjustable from 0~99 hours. Users can configure upper/lower voltage limits, discharge power and stop conditions as required.
Q9: What cooling method does it adopt?
A9: Air cooling. If any cooling fan fails or has open circuit, the tester triggers an alarm and trips the load automatically.
Q10: What data can this instrument measure?
A10: It measures active/reactive/apparent power, energy, RMS voltage, RMS current, power factor, phase angle, frequency and other key power indicators.
