The PDM1 is a powerful solid state relay with built-in overcurrent protection in a small, completely sealed enclosure. Manufactured in the USA and programmed to support continuous 20-amps, it is an intelligent power distribution module that eliminates the need for fuses as is the case with conventional normal and solid state relays. A built-in RGB LED light shows operating conditions and will change colors during overcurrent conditions and will also let the user know when the unit is automatically retrying to activate the circuit after a protection shutdown. The CNC aluminum case is actually smaller that a standard ISO relay and can be mounted in any position. The electronics are fully enclosed in high grade epoxy resin making the entire unit completely waterproof. Internal pullup resistors on the inputs make this unit ideal for controlling nitrous solenoids since it will not "auto-fire" during initial ignition switch Key-On, eliminating the need for DPDT switches and simplifying your nitrous wiring. And it can also be pulse-controlled (PWM) with any square-wave signal up to 1000 times per second. Switching from a conventional relay to a PDM1 is extremely easy and only requires an additional ground signal (low current) wire to be connected. The PDM1 also features an internal microprocessor that monitors current spikes and prevents false overcurrent protection on inductive loads like fans and fuel pumps. By continuously monitoring current, the PDM1 will allow a brief spike that is normal on all inductive devices before entering protection mode. It also features "flyback" protection against negative voltage generated by fans and other inductive motors. Detailed wiring and PWM control instructions are included
