Voltage Sensitive Relays/ LVD A single, high current module to handle all your LVD needs Highest performing low Voltage disconnect on the market One input from the battery One output post for all high and low current accessories Decreases vehicle downtime and lost productivity due to discharged battery High and low Voltage cutoff Over-current protection Over-temperature protection Short circuit protection Timers and delays Manual override trigger Manual activation trigger Transient self-protection Fully autonomous operation Industry-leading, ultra-low on-state resistance Internationally patented arrayed MOSFET technology No heat sinks or airflow required No de-rating required over full temperature range Fully encapsulated solid state design Conventional Low Voltage Disconnects typically require external mechanical contactors to drive loads of any significance. Multiple relays and wire/cable runs create unnecessary installation complexity, drive up maintenance costs, and create a basic level of brain-damage fleet operators can do without. If only there was a device that served as a Low Voltage Disconnect, but could also handle ALL the accessory loads thus eliminating the need for external contactors. POWER-GATE Voltage Sensitive Relays are your solution. IMPORTANT: If you have a Balmar External Voltage Regulator connected in the system please advise so that we can program the trigger time to one minute (Balmar regulators have a 35 second delay before they power up).

Perfect Switch Relay Information

POWER-GATE Solid State Relays are constructed based on their patented arrayed MOSFET technology. MOSFET transistors have an integrated body diode and depending on the application's direction of current flow, two primary configurations of POWER-GATE Relays are offered: uni-directional and bi-directional. All relays can be manually controlled, autonomously controlled, or a mix of both manual and automatic features.

Uni-Directional Relays are designed to sit between a source and a load. Some examples would be a relay sitting between and battery and a motor, or between a battery and an inverter. Current will only flow in one direction from the battery to the load its powering.

Uni-directional Relays can be controlled manually, triggered when the user applies system Voltage to the device's trigger input. When trigger is applied the relay closes (conducts current), and when trigger is removed, the relay opens (ceases to conduct current). They can also be configured to work autonomously where the on-board micro controller decides when to conduct current, or not to conduct current based on system Voltage, timing, or current cues. With this kind of flexibility built into every relay, devices can be configured to serve as:

ISOLATOR DEVICES/ RECTIFIERS

POWER-GATE Battery Isolators are industry leading, high performance, one-way electrical valves. They are commonly deployed in multi-battery applications where independent discharge or battery separation is required. Never confuse conventional battery isolators with POWER-GATE battery isolators. POWER-GATE devices enjoy ultra-low on-resistance and require no heat sinking and no airflow at currents up to 600 Amps.

Recommended by EnerSys (manufacturer of Odyssey, Hawker, Loadhog, Powersafe, General, NP, Ironclad, Genesis, Heritage, and Varta batteries), and utilized in both military and civilian applications, POWER-GATE Battery Discharge Controllers insure that power gets to where it's needed without the excessive heat and Voltage drop typified by more common, lesser performing silicon and Schottky devices. Unlike conventional silicon and Schottky isolators, POWER-GATE's achieve sub-100 micro-ohm performance, even as the currents climb through 600 Amps; that's over 1,000% more efficient than traditional silicon and Schottky technology. With heat being the primary killer of electronics, engineering heat OUT of the product yields unparalleled reliability.
