Massively reduces the charge time of battery banks via engine running. I can charge to full in an hour with a 1000ah domestic battery bank. Older model but still the most powerfull due to the heat sink and fan. See image for comparison spec. Newer models are just plastic casing for added water proofing but are not as powerful for boosting lower powered alternators.
Pro Reg D advanced alternator regulator (includes two temperature sensors). Voltage: 12 & 24 DC. Size (L x W x D): 180 x 90 x 55mm. Positive field control 25A max field current. Negative field control 30A max field.
Up to approx 600A alternator, more if a negative field control. 400A if stand alone, without existing regulator fitted. Please note advanced regulators are not suitable for some modern vehicles / boats with integrated engine management systems as they increase the alternators voltage and this can be interpreted by the management system as a fault on the alternator.Please use an Alternator to Battery Charger or a Battery to Battery charger for these applications. Digital software control with slow start Digital control (software) uses lines of computer code, digitally burned into a memory processor in the Advanced Regulator. This means that very complex information and mathematical algorithms can be processed that would not be possible with an analogue hardware system. The unit ramps up the current over a short period of time to reduce the chance of alternator belt slip. Dynamic progressive battery charging This is a term used to explain that the internal software calculates a different charging regime every time it is used as the battery state etc.
Older systems simply used fixed trimmers which were not able to distinguish different battery types or sizes. Can be used in parallel or a stand alone reg This unit can be used as a stand-alone regulator as well as in parallel with the original regulator. Sterling believes that, where possible, to leave the existing regulator in place this offers the Sterling Reg a fall back safety position in the event of it failing.Programmable for different battery types Most other manufacturers fail to recognize the fact that the world has more than one type of battery. There are now four main groups, open lead acid/traction, sealed /gel, gel (Europe) and AGM To optimise charging for each of these battery types there are four totally different charging curves, temperature curves and safety criteria with each battery type. Single unit fits 99% of alternators The reason for this is very simple, if you check other makes, you can find 12-15 different models to cover what the Sterling will do with 1. The problem with this is the public must supply correct information about their alternator and batteries to ensure they receive the correct Advanced Regulator. Charges to 4 step constant current progressive charging curves All good battery chargers are constant current with 3 4 step charging curves. This method is recognized as the best charging type so why expect anything less from your alternator- in most cases the primary battery charging source.
The Sterling Advanced Regulator converts your basic constant voltage alternator into a modern 4 step constant current battery charger, its that simple. Self diagnosing fault findings The performance and benefits of an Advanced Regulator are beyond dispute, however, an Advanced Regulator which has been incorrectly installed or fails, can have devastating effects on a boat.It will destroy the batteries and could easily set fire to cables. Sterling takes all this into account and recognizes that some boats on which these regulators are used have poor wiring and other faults. Because of this we scan the system every two seconds and if all the parameters are not within our pre-set values then the unit will switch off and signal a fault. This, in my opinion, is the most important aspect of this type of device, a point not shared by our competitors.
Totally isolates the regulator in a fault condition This is very important and not fully understood by the public. All regulators can fail for different reasons. If an Advanced Regulator fails closed then the alternator will work at full power and destroy everything around itself. Simply turning the regulator off will have no effect, so in the event of a Sterling system failing or tripping, for whatever reason, we physically break the field wire guaranteeing that the Advanced Regulator will stop working.Information 10 LED display Most Advanced Regulators have no real information being transmitted to the operator and as a result one has no idea what is going on. Depending on the model we give the operator as much information as possible as to what is happening with the product and the installation system in general. Battery temperature sensing One battery temperature sensor is supplied with the unit. This will adjust the output charging curves with the ambient battery temperature.
High battery temperature trip Most Advanced Regulators monitor the battery temperature to perform the task as explained above, but what is the point of monitoring the temperature if in the event of a battery going over temperature you do nothing about it? High battery voltage trip In the event of the battery voltage going too high the unit will switch the regulator off and display a warning. High alternator voltage trip This is the most common trip used. In the event of poor wiring, incorrect installation, or any fault in the system, the alternator voltage will rise too high; the unit will trip out and display a warning. De-sulphation ability on open lead acid batteries In order to prevent and even de-sulphate lead acid batteries a regular charge cycle exceeding 14.4V (x 2 for 24V) will remove the sulphate from a battery bank and so prolong its life expectancy.
In event of failure auto return to standard regulator There are many good reasons to leave the standard regulator in place, one of them being that, in the event of a Sterling failure or any trip condition of the advanced regulator, your standard regulator will automatically take over and allow the journey to continue but at a lower charge rate. If your Advanced Regulators does not offer this feature then you will lose the use of the boat during any failure. Most other makes insist a temperature sensor be fitted.The item "Sterling Pro Reg D Universal Advanced Alternator Regulator" is in sale since Sunday, September 5, 2021.
