Product Features
AC/DC Adjustable RCD Composite Load:
High-precision resistance unit with ±3% resistance accuracy and ±10% capacitance accuracy, capable of real-time display of voltage, current, power, power factor, and reactive power parameters.
Mandatory forced air cooling (front-in, rear-out):
Supports 24/7 continuous online operation, with a resistance design lifespan of 15 years.
Multiple security protections:
Integrated with overcurrent, overvoltage, high-temperature alarm, fault alarm and emergency stop functions; IP20 protection, suitable for indoor environments.
Application Scenarios
Inverter, energy storage converter, UPS (Uninterruptible Power Supply) factory aging test and type approval test
Verification of load capacity, aging and reliability of charging piles and AC power modules
Laboratory power equipment research and testing, simulating resistive + capacitive composite load conditions
Load verification and discharge testing of the generator set and emergency power supply
Common Questions & Answers
Q1: Does this load cabinet support remote control?
A: This model does not have remote control function. It is controlled locally using circuit breakers through manual operation.
Q2: Can both the resistance and capacitance be adjusted simultaneously to simulate different power factors?
A: Yes, with the RCD composite load, the resistance and capacitance can be freely combined in multiple settings, and the power factor can be adjusted within the range of 0.7 to 1.
Q3: What are the limitations of the working environment?
A: Yes, the equipment supports 7*24h continuous operation, but it is necessary to ensure good ventilation and normal operation of the fans; the environmental temperature must not exceed 50℃.
Q4: Is there any limit to continuous operation for a long time?
A: It supports 7*24h uninterrupted continuous operation. Under normal resistance conditions, the service life can reach 15 years.
Q5: How is the voltage switched?
A: It supports two-level switching between AC120V and AC240V for use, and the auxiliary power supply is AC220V.
