mjpower-ss
It’s another new product day here at mjbots! Introducing the mjpower-ss:
This provides many of the same functions as the power_dist r4.5b:
-
Pre-charge: High capacitance, low-impedance loads up to 4000uF will be safely turned on in a controlled manner.
-
Undervoltage and overcurrent protection: If the instantaneous current exceeds 100A, a soft circuit breaker is engaged.
-
Connector multiplexing: 1x XT90 input feeds 6x XT30 output connectors which are wired in parallel.
-
External switch: An external illuminated switch is supported, with the same connector and pinout as for the power_dist. A switch harness can be purchased separately.
It does have a few differences from the power_dist. First, it does not have computer monitoring or control. Thus there is no CAN-FD port. Second, an onboard switch is included, which can be used in place of the external switch. Third, it is both smaller (50x70mm vs 50x80mm), and cheaper ($84 vs $149).
Finally, our current manufacturing lot of power_dist r4.5bs had its maximum voltage derated to 10-44V. The mjpower-ss is rated to the same 10-54V that moteus-n1 and the pi3hat are. This allows it to be used with 48V systems and 12S lithium batteries.
