DC TO DC CURRENT LIMITING VOLTAGE SENSITIVE RELAY 280A 12/24V
[CVSR280]

STERLING PRODUCTS CURRENT LIMITING VOLTAGE SENSITIVE RELAY 12/24V AUTO SELECT 280A.

These relays have current limiting built in,in a nutshell your can do whatever you want with them and if you overload them they simply switch off safely.

With a current limiting VSR in an overload situation the overload will surge through the relay for a split second (within the relays capability) then the current limiting device will see this overload and reduce the current from a dangerous amps situation to a very safe 6 amp load and not a high load and so protect the relay and your installation and once the high load is removed the relay is safe to re-engage and continue its job.

The range of CVSR have full adjustment abilities and comes comes factory set to bi directional activitation and can be fitted with no adjustments required to operate as a voltage sensitive relay staright out of the box, it is auto voltage adjusting so it can fit to a 12V or 24V circuit however the following things can also be adjusted if desired.

UNIT DIRECTIONAL ACTIVATION
FUNCTION 1.Charging activated by starter battery voltage increase(engine on) This is the most common setting and also does not have an ignition feed requirement.This connects the primary and secondary banks based on a voltage in excess of 13.3V being sensed on the primary battery only (the engine start bnattery), The 2nd battery bank once connected would only disconnect when both batteries drop below 13.0 volts on both sides.The 13V safety threshhold is still activated to protect and seperate the batteries if , or when, the drain that invoked this function (voltage drops below 13V) once the unit has tripped and will not re-engage until the voltage on the primary battery bank ( the engine start) has again exceeded 13.3 volts. No ignition feed is required for this setting.

FUNCTION 2.Charging either way (bi-directional),based on voltage rise on either side of the unit (default setting).This function will close the relay at 13.3 volts sensed on either side of the relay, a good example of this would be the use of a combi inverter charger on the domestic battery bank, because most combi's only have a single output charging line (to the domestic battery bank) then with this function the unit will charge from the combi to the starter battery bank (in effect giving you 2 outputs from the battery charger) when the combi is on, but also charge from the alternator to the domestic bank when the combi is off. In either mode the unit still has the 13.3V on and 13V off mode and the current limit factor. No ignition feed required on this setting.

FUNCTION 3. Charging batteries one way only. This function allows a charge to flow from an alternator or battery to battery charger, or any other source to a secondary battery bank, but only when the engine is running. In effect this mode only allows current flow from the primary flow to the secondary, and will continue to flow until there is either an overload threat or a low voltage threat to the primary battery or the engine is shut down. This function requires an extra wire to the unit, an ignition feed, that informs the unit if the engine is running or not.

VOLTAGE PARAMETER ACTIVATION: voltage activation and deactivation parameters can be adjusted using the setup command.
Auto 12.24 volt selection, the unit will auto select the system voltage using the following, if it senses 4 to 16 volts it will select 12 V, if it sees 16 to 30 volts it will select 24V and if for some reason the input voltage is very low ( in the case of an empty 24V system) then the unit can be disconnected and allowed to re-engage, once locked the unit will hold that setting until fully isolated again.

The CVSR is fitted with the latest active progression disconnect algorithm to ensure that the batteries can charge even where large differential voltages exist. As such there will be various time delays between what the customer has pre set as the turn off voltage point and the product actually turning off.The time delay will reduce the lower the voltage is below the programmed disconnect voltage.
