The UL Recognized (E509290) JEM Power Shedder offers precise ON/OFF control for four conditioned and two unconditioned 74 VDC power outputs. Featuring an Ethernet port for seamless communication with external devices and the JEM PS Config Tool for data acquisition and programming, it also includes three inputs for output power state control.
Designed for use with the Power Line Filter (providing input circuit breaker, surge protection, and clean 74VDC power), the Power Shedder is available in two-panel configurations integrating the filter, shedder, and load circuit breakers.
Specifications
- Typical operating input voltage is 51.8 to 92.5 VDC.
- Maximum input voltage is 92.5 VDC.
- Typical current draw is 80 mA with outputs turned OFF.
- Maximum current is 10A for each output, but not more than 20A total for all six outputs combined.
- Four conditioned 74 VDC output ports (1 through 4) maintain output voltage above 52 VDC during short-duration power sags lasting less than 10 seconds (+/- 4 seconds) when the combined current for all four of the conditioned ports is less than 10A.
- Two unconditioned 74VDC output ports (5 and 6) simply follow the input voltage.
- One IEEE 802.3 10/100M front panel port.
- 8 pin M12 interface (A coded).
- Multicast message sent until shutdown timer expires indicating a shutdown sequence in progress.
- Three 74 VDC input control lines.
- Knife sense monitors + terminal a circuit associated with the Knife Switch cold side to indicate Knife OPEN/CLOSED.
- Engine sense monitors the + terminal of a circuit associated with Engine ON/OFF.
- Aux sense (future) is not currently used.
- LED status of Output Active, Link/Activity, and Processor Health.
- Auto wake-up periodically powers select outputs on a scheduled basis for a configured amount of time.
- Access Self-Test diagnostics and event data log files using the JEM PS Advanced Config Tool.
- FCC Part 15 Sub-part B Class A.
