技術指定

Working Principle

The load bank integrates resistive elementsそして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.

• 冷却システム: 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

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

• UPS システム: Long-time aging tests and reliability verification.

• 再生可能エネルギー: Grid-tie inverter and photovoltaic system validation.

• データセンター: Simulating real IT load for facility acceptance.

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

なぜGROADAを選ぶのか？

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:

• 評価された力 ≥ 1.2 × tested equipment rated power.

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

• パワーファクター: 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.
