CTEK SmartPass 120


SKU: CHG-CTE-SP Category:


The CTEK SmartPass is an energy management unit which controls and optimises energy produced by alternators, solar cells, wind power or conventional AC/DC chargers, and distributes it to the battery banks or consumers which require energy, such as the deep cycle bank, bow thruster batteries, consumers, etc.

Used together with a D250S, SmartPass provides optimal charging via CTEK???s unique staged charging cycle, which also protects your batteries. SmartPass also has an integrated ???battery guard??? which protects deep cycle batteries from harmful total discharge and ensures that critical equipment such as radio, emergency lights and navigation systems always function. SmartPass has a temperature sensor which protects batteries against high temperatures.

SmartPass is a fully automatic energy management system which can handle up to 80A for batteries of between 28-800Ah. The energy management system is IP65 classified (water jet and dust protected and approved for outdoor use). Suitable for all types of 12V lead-acid batteries.

Features & benefits:

  • Battery separation eliminates diodes and VSR relays.
  • Charging of service batteries up to 100 A, reducing recharge time.
  • Separation of energy-consuming equipment and service batteries during charging increasing the expected life of 12 V devices such as light bulbs, LEDs and other electronics. Allows the battery to be charged from the alternator at a level that minimises recharge time.
  • Temperature protection of services batteries reduces charge current at high temperatures.
  • Maximised battery life as a result of reduced incidences where the battery is undercharged.
  • Reduced charging times and costs by decreasing engine idling.
  • Reduced dependency on AC power onshore through efficient use of alternator and solar power
  • 2 year warranty.
