| The MiniPort Series Power Relays are remotely controlled relays that switch 120 VAC. The MP-15 handles 15A, the MP-20. 20A, and the MP-30. 30A. Control is via a full-size terminal strip that allows remote control via safe, inexpensive, low voltage Class 2 control wiring. The MP-15 and MP-20 are UL and C/UL listed; the MP-30 is pending. MiniPorts can be controlled from a remote location with either maintained or momentary contact switches such as the Furman RS-1 or RS-2 system control panels. For single switch locations, use the RS-1. When the system needs to be controlled from more than one location, use the RS-2. Multiple MiniPorts may be connected together 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, 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. Please note that turn-off is simultaneous, however. A Furman PowerLink or ASD-120 Sequenced Power Distro can also be used to control MiniPort(s), expanding their current-handling capacity with an additional 15, 20, or 30 amp circuit per MiniPort. In this use, the MiniPort(s) are connected to the control terminals on the PowerPort or ASD-120, which provide the necessary switching function. With the addition of a PS-REL AC Relay to provide switching, a MiniPort can be used to extend the capacity of a Furman PS-8R or PS-PRO Power Sequencer -- or, for that matter, any product with a switched outlet, such as a receiver/amp 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. Both the MP-15 and the MP-20 come equipped with two knockout holes for permanent installation with 1/2" conduit -- one on the top surface, the other on the bottom. Use of the bottom knockout hole requires removing the AC cord. According to the National Electrical Code, 1/2" conduit can accommodate up to five 20 amp circuits using ten THWN 12 gauge stranded wires; however, local codes should be checked for exact requirements. All models include an internal 12 VDC supply, and are housed in rugged steel enclosures. The MP-15 and MP-20 come equipped with heavy duty, 10 foot AC cord and are UL and C/UL listed. The MP-30 has a NEMA L14-30 twistlock inlet and outlet, with multiple knockouts in various locations. Click here for more information |
