The idea is that when the connected engine with alternator is started, the voltage of the primary battery increases above 13.2V, the VSR activates to combine the primary and secondary battery.\u003c\/p\u003e\n\u003cp\u003eThe issue comes when the downstream device being linked is a high current draw device that causes the primary battery voltage to dip.\u003c\/p\u003e\n\u003cp\u003eFor example, using a DC\/DC charger in your boat to charge a Lithium trolling motor battery. The DC\/DC charger can draw 30A when operating which is great if your outboard can deliver 30A but many outboards will struggle to provide this output, especially when the engine is at idle. Using a standard VSR for such applications will see the VSR 'door belling' or clicking 'on and off' in short succession essentially starting and stopping the DC\/DC charger and making and breaking the electrical connection as the voltage of the battery cycles down and up. Using ordinary VSRs this cycling can happen every 15 seconds which causes the VSR to heat at it's relay contacts and quickly fail.\u003c\/p\u003e\n\u003cp\u003eUsing the Trolltek™ Programmable VSR gives the user more options on how best to configure their system. For example, the disconnect voltage be adjusted down to 12.3V. A lead acid battery is still at ~70% state of charge at 12.3V so this is a acceptable voltage to disconnect. Additionally, the user can further set a time delay for the disconnect event. For example, when the battery voltage drops to 12.3V, run the charger for a further 5mins before disconnecting it. This wider operating band makes a massive improvement to the overall operation and reduces the cycling of the relay. It also allows for periods of idling the engine and reduced alternator output without the potential of accidentally flattening the primary battery.\u003c\/p\u003e\n\u003ch3 class=\"p1\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003e\u003cspan color=\"#9e2d21\"\u003eDESIGNED FOR MARINE\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eTrolltek™ PVSRs are fully potted and housed inside a enclosure ensuring they last in the harsh marine environment.\u003c\/p\u003e\n\u003ch3 class=\"p1\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cstrong\u003e\u003cspan color=\"#9e2d21\"\u003eHEAVY DUTY 150A RELAY \/ 250A INTERMITTED\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eThe \u003cspan\u003eTrolltek™ PVSR is suitable for switching continuous loads up to 150A which provides ample capacity for most uses.
