技术规格

Working Principle

The load bank integrates resistive elements and inductive coils in modular sections.

• Load Control: PWM control enables precise step adjustment of load capacity.

• Power Factor Simulation: Supports real-time adjustment to simulate inductive and capacitive conditions.

• Protection Mechanism: Temperature sensors, fan monitoring, automatic unloading in case of fault.

• 冷却系统: High-volume fans ensure fast heat dissipation and safe operation under full load.

• Smart Monitoring: Remote control and data logging via Modbus or Ethernet.

Application Scenarios

• 发电: Testing diesel / gas generators under full load and transient conditions.

• 不间断电源系统: Long-time aging tests and reliability verification.

• 可再生能源: Grid-tie inverter and photovoltaic system validation.

• 数据中心: Simulating real IT load for facility acceptance.

• EV Charging Stations: Power electronics and charging infrastructure testing.

为什么选择GROADA？

Compared with traditional load banks, GROADA AC load banks deliver:

1. Higher accuracy in power factor adjustment.

2. Better thermal management with forced air cooling.

3. Modular and expandable architecture for flexible capacity.

4. Advanced safety protections ensuring long service life.

5. Remote monitoring & control for modern test environments.

Selection Guide

When choosing a load bank:

• 额定功率 ≥ 1.2 × tested equipment rated power.

• Voltage Level must match system (300–380V standard, custom for 400/415/480V).

• 功率因数: choose RL load bank if your DUT (device under test) involves inductive / capacitive behaviors.

• Environment: outdoor use requires higher IP protection and enhanced cooling.

FAQ

Q1: Can the load bank run continuously at full power?
Yes, with proper ventilation, it can sustain continuous full-load operation.

Q2: How often should maintenance be performed?
Every 6–12 months: check fans, wiring terminals, resistance modules, and clean dust.

Q3: Does it support remote monitoring?
Yes, via RS-485 / Modbus / Ethernet for data logging, alarm, and control.

Q4: What protection functions are included?
Overload, overheat, short-circuit, and fan failure detection with automatic load disconnection.
