Description
The Roc 2500 is the first product from a new generation of intelligent, high-powered, 230v Hotline energisers. The Roc 2500 is a 7 stored joule energiser with a 25 joule boost mode that will handle most unforseen problems that may bring your fence voltage down to an unsecure level. The LED fence indicator offers a quick visual guide on how efficient your fence is operating while the LCD screen gives you detailed voltage information. There are two user defined low voltage alarms that can be set in the menu which can drive a 12v external siren (not included) to give real time warning if your voltage drops below the required level. Battery back up connection will mean seamless use in the event of mains power loss. The indicator will monitor the battery charge level, which will be trickle charged when mains power is available.
