Furman MP30

The MINIPORT-30 Power Relay is a 30 amp, contactor switched 120 VAC outlet, with a terminal strip that allows remote control via safe, inexpensive, low voltage Class 2 wiring. The MINIPORT-30 provides a twistlock inlet and outlet, and is housed in a heavy duty steel, 8" x 8" x 4" junction box.

This model includes an internal 12 VDC supply, and can be controlled from a remote location by using the Furman PowerLink Remote AC Power Sequence Controller, the ASD-120 Sequenced Power Distro, or for simpler jobs, the Furman RS-1 or RS-2 Remote System Control panels. The RS-1 provides a maintained key switch; the RS-2 has a momentary switch.

Multiple MINIPORTs have their control wiring paralleled so that all are controlled by a single switch closure, and may be linked so that all turn on simultaneously or one by one, in a delayed sequence. If delayed operation is chosen, the delay interval between the turn-on of one MINIPORT and the next is approximately 3 seconds. (Delayed turn-on is useful in avoiding large inrush currents that can trip house circuit breakers, that would otherwise occur if all amps were turned on simultaneously.) Turn-off always occurs simultaneously.

All four sides of the enclosure have multiple knockouts to accommodate every installation, with 3/4" conduit- one on the top surface, the other on the bottom. According to the National Electrical Code, 3/4" conduit can accommodate up to eight 20 amp circuits using sixteen THWN 12 gauge stranded wires; however, local codes should be checked for exact requirements.

With the addition of a Furman PS-REL AC Relay to provide control, a MINIPORT can be used to extend the capacity of any other product that has a switched outlet, such as a receiver/amp that is then controlled with a wireless remote. When used in this manner, the MINIPORT is switched on or off when the outlet that the PS-REL is plugged into goes on or off.
