Small size SSPC - system size reduced by 45%
The LEACH solid-state power controller has a small-sized SSPC with reliable, fault free switch function and true short-circuit and overload protection.The load current can be sensed and the shutdown can be initiated within microseconds.Generate a status signal from the load current value or load voltage value, and report the status signal through optical isolation state output.These devices are designed to operate in a 28VDC system, so there is no need to reduce capacity for any load type.They are sealed in metal packaging.For other rated values and operating voltages, please consult LEACH.When the working temperature reaches up to 85 ° C, there is no derating for all types of loads.
Multiple options for rated current:
1A； 2A; 4A; 5A; 10A
This LEACH solid-state power controller is characterized by reliability and has free switching protection for actual short circuits and overloads in case of frequent faults. Sensing load current and within microseconds. Derive status signals or load voltage values from load current values and output them through photoisolated status reports. Designed for 28VDC systems, but these devices do not require derating for any load type. They are sealed in a metal packaging. For other rated values and operating voltages, please consult with Weikewei technicians
Pay attention to the following 9 points:
1. Observe the thermal derating treatment. The available ratings can be found on the homepage.
For versions with a current of 4 amperes and higher, the maximum voltage drop is 300 millivolts. The load current is 100% of the rated current.
3. If the reverse polarity is not blocked, it may damage the SSPC.
4 at 100 ° C and 28V.
5. Maximum duration of 50 milliseconds, duty cycle=1%, repetition rate of 1Hz.
According to the time specified in MIL-P-81653.
7 See "Trip Characteristics".
