Product characteristics
CPM-R series fuse combination power supply SPD has built-in short-circuit protection device, which does not need additional fuses or circuit breakers. It is better to simplify the complex.
1. Lower residual voltage: avoid the larger residual voltage generated by the windings and connecting wires of the fuse itself when the fuse is installed separately. The effective reduction rate of residual pressure exceeds 50%.
2. Faster response speed: nanosecond response speed, the maximum response time is less than 25ns, and the overall characteristics are comprehensively improved.
3. More convenient installation: the 35mm standard guide rail is installed, and the compact size ensures the universality of the installation range, saves space and saves the installation cost of the power distribution cabinet.
4.N-bit advantage: No matter which level of line discharges lightning current, the path is the shortest and the residual voltage is further reduced.
5. There are also hot backup dual-chip products, such as CPM-R40TA and CPM-R40SA. , hot backup lightning protection module, national patented technology, to provide deeper protection.
Therefore, CPM-R series products are the replacement products that simplify complexity and improve performance.
Application mode
1. Select product order number: select product order number according to technical parameters such as working voltage and isolation voltage of electrical equipment;
2. Installation: The base is installed on the 35mm standard guide rail, and the power cord is crimped in the wiring hole.
3. Grounding: Multi-module CPM-R only needs to be connected by grounding (PE) once.
Description:
When the lightning protection module is damaged due to overload or power frequency overcurrent, the built-in circuit breaker will act in time and the fault indicator light will be on. At this time, the built-in circuit breaker of CPM-R must be replaced in time.
When the lightning protection module fails, the color of the fault indication window of CPM-R changes from green to red. At this time, the lightning protection module of CPM-R must be replaced in time to protect CPM-R.
Our company also supplies similar products of the above products: CPM-R80t, CPM-R 100t and CPM-R20t.
