400 kW high-power output; 1 kW precision stepping capability; high power factor for accurate simulation of real loads
High-precision segmented load adjustment, simulating real-world loads:With a high power output of 400 kW and a minimum adjustment step of 1 kW, multiple settings can be combined; featuring resistance accuracy of ±3% and a power factor of 0.99. The lightweight design with casters makes it easy to transport and install.
Operates stably around the clock with a long service life:When operating forward, it switches to forced air cooling for efficient heat dissipation; supports 24/7 uninterrupted online operation with a resistor design that lasts up to 15 years, ideal for long-term aging tests.
Comprehensive security protection tailored for various operating environments:Integrated overvoltage, high-temperature, and fan failure alarms with emergency stop functionality; IP20 indoor protection rating; wide operating temperature range of-10°C to 50°C; stable current carrying capability via copper busbar wiring.
Dual control system with local touch screen and remote RS485 interface, compatible with automated production lines:View voltage, current, and power data in real-time on the touch screen; supports PC-based programming and can be connected to automated aging lines or laboratory testing systems.
Q1: Is this device compatible with AC 230V power supplies and suitable for testing overseas power products in Europe and America?
A: Fully compatible; specifically designed for overseas 230V single-phase devices and compliant with mainstream voltage standards in Europe and America.
Q2: Can an IP20-rated device be used outdoors?
A: Not recommended for outdoor use. With an IP20 rating, it lacks water and dust resistance and is only suitable for dry, well-ventilated indoor environments. For outdoor applications, a rain-resistant enclosure must be installed or a dedicated outdoor model should be selected.
Q3: Is long-term operation at full load prone to overheating and damage?
A: No, the device features a variable-speed air-cooled cooling system that automatically triggers alarms and cuts off power when overheating or fan failure occurs; proper maintenance ensures round-the-clock operation.
Q4: Does it support remote automatic control from a computer?
A: Supported; comes standard with RS485 and the universal Modbus protocol, compatible with both domestic and international host computers.
