CTEK D250S, SmartPass User guide

MANUAL

CONGRATULATIONS

on the purchase of your new CTEK professional battery management unit. This unit is part of a range of professional battery chargers from CTEK SWEDEN AB. It represents the latest technology in battery charging. Using the CTEK D250S DUAL and SMARTPASS products, you can maximize the performance of your 12VDC source.

SAFETY

•The unit is designed for 12V lead-acid batteries. Do not use the unit for any other batteries.

•Use safety glasses when connecting or disconnecting a battery.

•Battery acid is corrosive. Rinse immediately with water if acid comes into contact with skin or eyes. Seek medical advice.

•Make sure that the cables are not being pinched and are not in contact with warm surfaces or sharp edges.

•While charging, a battery can emit explosive gases; avoid sparks in the immediate area.

•Always provide for proper ventilation during charging.

•Avoid covering the unit.

•D250S DUAL is not reverse polarity protected.

•Disconnect battery poles before installation

All installations on boats must follow ISO 10133. Please note!

1.Connections from the battery must be fused close to the battery.

2.Batteries must be permanently mounted in ventilated areas.

3.Cables must be placed in tubes, separated from cables for 230V (shore power), or be attach to the surface every 300mm.

4.Cables in the engine room must be rated to withstand 700C

D250S DUAL

The D250S Dual has 2 inputs. The Service battery will be charged from the alternator, solar panel, or both in combination. The solar panel adjusts itself to the Starter battery voltage. The Starter battery will be charged and maintained directly by the solar panel if the Service battery is fully charged.

features:

•Multi-step 20A temperature compensated battery charging and battery maintenance.

•Battery separation of Starter and Service batteries.

•Maximum power point tracking for solar panels charging the Service battery.

•Two power source inputs (alternator, solar, wind, Supply battery and other).

•Coordination of the two inputs, allowing parallel operation.

•The auxiliary input will also charge and maintain the Starter battery.

SMARTPASS

SmartPass can operate as a stand-alone unit, but works best in combination with D250S Dual. The SmartPass creates a priority path for charging the Service battery to recharge it more quickly and efficiently. Attached energy sources like solar, wind or shore power will charge both the Service and the Starter batteries through the SmartPass. Service batteries that are overheated due to age, high ambient temperature or other battery problems will be protected from high alternator current.

SMARTPASS

fEATURES:

The CTEK SmartPass adds additional functionality for higher output alternators, larger battery banks and/or high parallel loads.

•Separation of consumers and Service batteries during charging, which improves the charging capacity significantly, and lowers the consumer voltage, which increases expected service life of lights and other electronics.

•Service battery watch, which avoids harmful deep discharges that otherwise would shorten battery life. The battery watch also protects navigation, radio and emergency light from being out of electricity.

•Over-temperature protection of Service battery. High battery temperature could significantly reduce battery life.

•Maintenance charge of Starter battery, which simplifies installation with fewer components. •Simplified installation of AC/DC chargers (shore power). Only one output from the AC/DC charger needed.
