The DPC-7500-120V is a unique lighting controller that connects to a 4-wire 240 Volt service but provides six 120 Volt outlets (5-15r) that allow you to run up to 60 amps at 120 Volts. In many cases, you can plug this unit right into an existing dryer-type outlet (14-30r). Built-in digital timer with battery backup. Six timed 120 Volt outlets (5-15r) provide up to 10 amps each ? the last two outlets can be set to constant power. Detachable trigger cord can override the built-in timer, so Powerbox? can be controlled by other devices. 5 ft main power cord ? plug & play (14-30p). Hand-built at their California factory.
