RKC-308C Circuit Breaker Comprehensive Tester
Darui Electric recommends this for you
RKC308C is a new generation high-voltage switch comprehensive tester developed by our company based on RKC-308A. From its core to its appearance, it embodies advanced technology and professional design, making it a professional-grade product for comprehensive testing and analysis of high-voltage switch mechanical characteristics.
It is suitable for comprehensive testing and analysis of mechanical characteristics of various voltage levels and types of high-voltage circuit breakers.
Main technical parameters: RKC-308C Circuit Breaker Comprehensive Tester
1 Working power supply: AC220V±10%, 50HZ
2 Recording method: front paper replacement high-speed thermal printer
3 Measurement channels: 12 time channels, 2 travel channels (linear and digital channels automatically identified)
4 Built-in operating power supply: DC20V∽270V adjustable/15A (maximum up to 20A), resolution: 1V
Voltage adjustment method: manual or fully automatic electric adjustment
5 External operating power supply: 0~250V (automatic identification of AC/DC), breaking capacity 20A
6 Trigger mode: coil current or any analog/digital input channel
7 Speed customization function: arbitrarily define the starting point of speed calculation on the travel curve
8 Display: 320×240 large-screen LCD can clearly display all test data, various curves, and real-time clock even under strong sunlight
