New Royal Premium Replacement Power Supply

 

The internal power supply in the Digital Cluster is a common source of problem with the Digital Cluster. Electrolytic capacitors dry out then short, the switching transistor leads break internally, and failed alternators and 24V jump starts can cause overvoltage which destroys the Varistor.

 

This is a completely redesigned, NEW, modern power supply which is an exact replacement for the factory power supply. This power supply was designed for maximum efficiency, which means less power dissipated inside the digital cluster. When the car is off, the Royal Premium power supply draws just microamps to preserve battery life when the car is stored for long periods of time. This is less than 10% of the standby power used by either the factory supply or the "Green" PTM replacement power supply!

 

It is made with modern low-mass surface mount components to minimize the effects of vibration and maximize reliability. It includes six (6) capacitors to filter the input, and another six (6) capacitors to filter the output, while still staying within the manufacturers recommendations. An onboard microcontroller monitors the output, and LEDs indicates both proper output voltages, as well as error conditions.

 

Signs your Power Supply may be defective

  • When the ignition is on, the cluster remains dark and the info can't be seen

  • Segments randomly flash jibberish on the dark LCD panels

  • The LCD or CLSTR fuses blow repeatedly

  • You see physical damage to the components of the power supply
