Jianhong has launched a 60KW dual-voltage RCD load cabinet.

The three-phase independent adjustable design helps power supply manufacturers worldwide reduce costs and improve efficiency.

Recently, Shenzhen Jianhong Jitai Technology completed the iterative upgrade of its JH-RCD-60KWA400A190-P-RS three-phase adjustable RCD smart load cabinet and officially launched it on the market. The new model supports dual voltage switching between AC400V and AC190V, features an integrated resistive-capacitive load design for handling independent three-phase unbalanced loads, and is widely compatible with factory reliability testing for products such as frequency converters, power supplies, UPS systems, charging stations, and new energy vehicle control systems.

• Dual Voltage Switching:Supports switching between AC 400V and AC 190V three-phase four-wire voltages, suitable for testing power supplies at various voltage levels; covers three-phase loads up to 60 kW/RCD 60 kVA and single-phase loads up to 20 kW/20 kVA, offering extensive power coverage.
• High-precision, adjustable nonlinear load:Power factor adjustable from 0.7 to 1 with step increments of 0.05; resistance accuracy ±3%, capacitance accuracy ±10%. Features three independent rating ranges (resistance: 30 Ω to 0.2 Ω; power: 50 W to 10 kW; capacitance: 100 μF to 20 mF), allowing free combination of ratios.
• Dual-mode intelligent control:Local touch-screen control with real-time, high-precision (0.5-grade) display of voltage, current, and power factor; remotely compatible with Modbus TCP+RS485 for connection to upper-level computers on automated production lines.
• Durable and Safe Design:Features forced top-in bottom-out air-cooled cooling with IP20 indoor protection; comprehensive alarms for overvoltage, overcurrent, high temperature, fan failure, and emergency stop; operates continuously 24/7 with a resistor lifespan of 15 years; includes casters for mobility and copper busbar wiring for easy installation and relocation.

• factory aging of power supply products: comprehensive aging tests for UPS systems, switching power supplies, vehicle-mounted power supplies, charging stations, and variable-frequency power supplies.
• Inverter and industrial control equipment testing: type tests for photovoltaic inverters, frequency converters, servo drives, and braking systems with electronic control components.
• Laboratory R&D Testing: Third-party testing institutions and R&D laboratories simulate nonlinear grid conditions and three-phase unbalanced grid operating scenarios.
• Quality inspection for new energy production lines: energy storage converters, factory-rated efficiency of vehicle-mounted chargers, load operation performance, and harmonic reliability verification.

• Voltage compatibility → Compatible with both high-and low-voltage products: Features dual voltage switching between AC 400V and 190V, enabling measurement of both industrial-grade 400V frequency converters and low-power 190V power supplies.
• The R+RCD resistor-capacitor adjustable circuit simulates a real power grid: offering flexible combinations of resistive and capacitive components with continuously adjustable power factor (PF) ranging from 0.7 to 1, accurately replicating nonlinear loads, harmonics, and power factor fluctuations in actual power systems, closely mirroring real-world equipment operating conditions.
• Three-phase independent load testing → Simulation of unbalanced power grid: Each of the ABC phases can be individually loaded or unloaded, accurately replicating industrial scenarios of three-phase power imbalance faults and complying with national standard type test requirements.
• Intelligent communication + round-the-clock operation → Compatible with automated production lines: enables remote communication integration with assembly line systems for uninterrupted 7×24-hour operation, suitable for large-scale automated product aging processes; delivers high-precision calibration levels required for meticulous laboratory research and development.
