D250SE
•The D250SE is a DC to DC battery charger for a dual battery system with a starter battery and a service battery.
•The D250SE charges the service battery either from an alternator or from a solar panel, or from a combination of both.
•The D250SE separates the batteries in a dual battery system and thereby replaces, for example, a separation relay, VSR (Voltage Sensitive Relay), diode isolator or a mechanical battery selector.
•The D250SE can be used on its own or in combination with SMARTPASS 120S. In combination, the D250SE and SMARTPASS 120S can charge at up to 140A.
•Starter battery is only available as lead-acid battery.
FUNCTIONS:
•Charging service battery from a conventional alternator (constant charging voltage)
The D250SE charges a service battery at up to 20A from the start battery when a conventional alternator is running. This function is switched off when the engine is not running to prevent discharge of the starter battery.
•Charging of a service battery from a smart alternator (with variable charging voltage)
The D250SE can charge a service battery at up to 20A from the starter battery when a smart alternator is running. This function is switched off when the engine is not running, so as not to discharge the starter battery. The Installation section describes how the D250SE needs to be connected in order to activate the smart alternator functions.
•Charging a service battery from a solar panel
The D250SE can charge and trickle charge a service battery from a solar panel at up to 20A. The D250SE uses MPPT (Maximum Power Point Tracker) to maximise the power from the solar panel.
•Separation of the starter battery and the service battery
The D250SE separates the starter battery from the service battery when the engine is not running.
•Temperature compensated charge voltage
The D250SE optimises the charge voltage by increasing the charge voltage at temperatures below 25°C/77°F and reducing it at temperatures higher than 25°C/77°F. The function is active in AGM and NORMAL programs only.
•Trickle charging of the starter battery from a solar panel
The D250SE trickle charges the starter battery from a solar panel at intervals of 3 seconds if the service battery is fully charged.
•Optimised charging of AGM batteries
The D250SE can provide a suitable charging voltage for optimal charging of AGM (Absorbent Glass Mat) batteries, which require a higher charge voltage than other types of lead-acid battery. The installation section describes how the D250SE needs to be connected in order to activate the AGM battery function.
•Optimised charging of Lithium batteries
The D250SE can provide a suitable charging voltage for optimal charging of Lithium batteries.

SMARTPASS 120S
•SMARTPASS 120S is a solution for supplying current to charge and manage consumers in a dual battery system consisting of a starter battery and a service battery.
•SMARTPASS 120S separates the batteries in a dual battery system and thereby replaces, for example, a separation relay, VSR (Voltage Sensitive Relay), diode isolator or a mechanical battery selector.
•SMARTPASS 120S connects the starter and service batteries together in order to charge them both from the alternator.
•SMARTPASS 120S protects the service battery from deep discharge which would damage the battery.
•SMARTPASS 120S supplies consumers from the alternator instead of from the service battery while the service battery is charging, which permits faster charging.
•SMARTPASS 120S can be used on its own or in combination with D250SE. In combination, the D250SE and SMARTPASS 120S can charge at up to 140A.
FUNCTIONS:
•Charging service battery from a conventional alternator (constant charging voltage)
The SMARTPASS 120S charges a service battery at up to 120A from the start battery when a conventional alternator is running. This function is switched off when the engine is not running to prevent discharge of the starter battery.
•Charging of a service battery from a smart alternator (with variable charging voltage)
The SMARTPASS 120S can charge a service battery at up to 120A from the starter battery when a smart alternator is running. This function is switched off when the engine is not running, so as not to discharge the starter battery. The Installation section describes how the SMARTPASS 120S needs to be connected in order to activate the smart alternator functions.
•Battery guard
SMARTPASS 120S disconnects consumers when the service battery voltage is low in order to avoid deep discharge, which would damage the battery. The consumers are reconnected after the service battery voltage has increased. Connect critical consumers directly to the service battery so they will not be disconnected if the voltage falls to lower than 11.5V.
•Start assistance
SMARTPASS 120S automatically connects the service battery to the starter battery for 10 sec to assist, if the starter battery on its own is unable to start the engine. After the start assistance function has been activated, SMARTPASS 120S will display a fault indication until starting has been achieved without using the start assistance function.
•Separation of the starter battery and the service battery
SMARTPASS 120S separates the starter battery from the service battery when the engine is not running.
•Assigning current source priority
SMARTPASS 120S can sense when the alternator is running and in that case supplies consumers with current from the starter battery to work with the D250SE and maximise charging efficiency. Otherwise the consumers are supplied with current from the service battery.
•Dynamic overcurrent protection
SMARTPASS 120S has overcurrent protection to shield the product. Overcurrent protection permits up to 350A to be sent from the alternator temporarily so that charging will be accelerated.
•Battery temperature protection
SMARTPASS 120S protects the battery by switching off charging if the service battery temperature rises too high.
•Starter battery trickle charging
The service battery trickle charges the starter battery without assistance from the solar panel or alternator to compensate for the self-discharge of the starter battery. The service battery charges in 3-second pulses when its voltage is higher that of the starter battery and the voltage of the starter battery is low.

INSTALLATION
1.Install the apparatus on a smooth surface where it can be fi rmly secured and where it is not exposed to fuel, oil or dirt. To obtain the correct distance, start by fi tting the two units together with the accompanying connector plate (see Figure 3) before they are fi nally fastened to the smooth surface.
2.Secure the apparatus with, for example, M4 or ST4.2 screws at each corner (see Figure 1).
3.Before connecting the cables, ensure that the negative terminal post on the battery is not connected.
4.Connect the cables to the apparatus connections by securing screws (M8) (see Figure 2). Use an Allen key - tightening by hand without a tool is not
enough. Max 6 mm ring terminals (see fi gure 5).
5.Use tape (see Figure 4) to secure the temperature sensor
to a clean fl at surface above the service battery. Position the sensor as close to the positive terminal post as
possible.
6. Connect the battery negative terminal post.
WARNING!
The D250SE and SMARTPASS 120S are not protected against reversed polarity. Disconnect the battery terminal posts before installation.
