DC Input DC-DC Heavy Duty Industrial and Military Grade 12V to 12V Lead Acid Battery Charger 30Amps

More DC DC battery chargers
24V to 12V DC/DC battery charger, heavy duty industrial and military Charger for 12 volt sealed lead acid, gel cell, or VRLA SLA batteries from a 24 volt  battery, truck, or golf cart
5Amp Heavy Duty, Industrial, Marine, and Military DC/DC chargers 15 Amp 24V Output
30A 24V lead acid charger with 12VDC input

These chargers are high efficiency power converters (switchmode), designed for the charging of of 24 volt lead acid batteries in 12 volt vehicles, marine, and cell tower applications. These are attractive, reliable, robust DC to DC battery chargers with high power output. They are relatively immune to vibration and shock. They and come in three versions, heavy duty, water proof and military grade. Designed specifically to work in Day Cab HVAC transport vehicle applications.

These converters have common negative, so they are not fully isolated, but can be used for almost all 12 volt applications. They feature a spark-free connection, available wide temperature range (-40°C to +55°C) and 3 year warranty.
