Hardwire Electronics PDM 25

Advantages Over Fuses and Relays

• Greatly simplifies system wiring and reduces system component count.

• Reduces the weight of the electrical system.

• Provides increased reliability over traditional systems using mechanical relays. 

• Solid state technology removes the problem of relay contact corrosion and relay bouncing in vibration heavy applications.

• Smart features such as indicator and wiper motor modes remove the need for extra control units.

• Current draw can be monitored and logged to pre-emptively detect faults.
