Hardwire Electronics PDM25 Power Distribution Module

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.
