CTEK – Smartpass 120S 120A Power Management System & 250SE 20 Amp Battery Charger – Kit

CTEK Smartpass 120S 120A Power Management System

CTEK Smartpass120S 120A Power Management System with 250SE B2B

A high power charging system for both B2B 12v Split charging and solar charging. Suitable for AGM and Lithium batteries up to 500Amp/h.

This single unit neatly combines powerful charge control from both solar input and also B2B charging from euro6 alternators (most vans 2018 or newer).

Smartpass 120S not only charges and supplies the battery and service equipment with 120A power, but it also separates critical equipment from non-critical to ensure that the radio, emergency lights and navigation systems always have power. Smartpass 120S is a 120A power management solution that distributes, controls, and maximizes the available power of your alternator to power batteries and service consumers. SMARTPASS 120S handles all 12V batteries between 28-800Ah. The battery protector of the unit will protect your service battery from total discharge and the built-in overtemperature protection reduces the charging current before the battery temperature is too high. SMARTPASS 120S is compatible with D250SA and D250SE 20A on-board chargers.

250SE 20 Amp Battery Charger Kit

Dual input 20A charger with selectable charge voltages

The D250SE is a fully automatic, 5 step charger that supplies up to 20A of power to any 12V lead-acid or ­lithium* service battery from 40–300Ah. It has ­selectable charge algorithms for AGM and lithium* batteries and can use power through its dual input from alternator and solar panel. When the service battery is fully charged, the D250SE will ­automatically redirect maintenance charge ­power to the starter battery. The D250SE can maintain a stable output up to 20A to vehicles fitted with smart ECU controlled ­alternators and has a temperature sensor for ­optimised charging, regardless of weather conditions. *) 12V lithium batteries (LiFePO4, Li-Fe, Li-iron, LFP)
