Electronic Circuit Breaker
S8V-CP - Electronic Circuit Breaker
S8V-CP protects DC circuits very precisely. Overload and short circuits are accurately detected and reliably switched off
- 4- / 8-channel electronic circuit breakers with adjustable tripping currents from 2 to 10 A
- Thermomagnetic tripping characteristic
- Sequential and load-dependent start-up of the outputs to avoid high inrush currents
- Ability to switch-on high capacitive loads reliably
- Backlit buttons with multi-color LEDs indicate the output status at a glance
- Push-In Plus terminal blocks
- Space saving Value Design for Panel
- UL Class 2 model reduces the costs of applying a safety standard

A voltage drop will occur in the S8V-CP. Consider
the voltage drop at the output. |

| Power consumption
2
When
selecting the power supply, be sure to include the internal power
consumption of the S8V-CP and not just the power consumption of
the load. |
When all outputs are connected |
10 W max. (at 10 A) | 3.1 W max. (at 3.8 A) | 20 W max. (at 10 A) | |
| When all output branches are tripped |
0.84 W typ. | 0.82 W typ. | 1.32 W typ. | ||
| Start-up
time
2
Outputs start in order from +VO1 to +VO8. +VO1 starts after
the initialization time. Start-up delay time of each output is automatically
decided depending on the load. If the start-up delay time is over
5 s, the next output is forcibly started. |
