High-voltage relay with 2 pole CO contact
The new, compact R300 high-voltage relay has been specially developed for use in modern test systems. It serves to ensure electrical safety during testing by isolating all non-active components during high-voltage and insulation tests. The robust and durable device is capable of safely switching currents of up to 25 amps during protective conductor testing. The open main contact system can withstand voltages of up to 10 kilovolts and can be easily integrated into various test environments. It offers a cost-effecient and safe solution for demanding test applications that require the highest safety standards.
Features
Modular configurable main contact system
Available in 1- and 2-pole versions for AC and DC applications. The contact system can be flexibly configured as a normally open or changeover contact to meet the specific requirements of the test system.
Permanently low power dissipation
The contact bridge with large contact tips ensures uniform contact and consistently low contact resistance.
Hassle-free load disconnection for continuous currents
The main contact system ensures reliable switching function for both positive and negative polarity, regardless of the direction of current flow. The bidirectional high-voltage relay thus enables hassle-free load disconnection for currents up to 25 amps, regardless of polarity.
Easy installation and high installation compatibility
Simple, screwless DIN rail mounting in accordance with industry standards. All connections for main contacts and coil drive with flat plug connections. No additional fastening components are required for installation.
Low energy consumption
PWM module for coil control with precise parameterization, low pull-in and holding power for reduced heat generation, and constant pull-in and switching behavior regardless of the ambient or coil temperature.
Maximum performance and protection
Due to its special design, the R300 has generously dimensioned clearances in the contact area despite its compact design. The open contact can withstand voltages of up to 10 kilovolts, which is significantly higher than the impulse withstand voltage required by standards.
Applications
- Test systems
- Multifunction testers
