Charge voltage can be precisely adjusted to suit any sealed or unsealed battery system.

In particular,sealed maintenance free batteries must be charged correctly in order to ensure a long service life.

overvoltage will result in excessive gassing and venting of a sealed battery. the battery will dry out and fail.

Quality without compromise

Alumimium epoxy power coaled cases with drip shield and stainless steel flxings withstand the rigors of an adverse environment : heat,humidity and salt air.

Circuit boards are protected with an acrylic coating for maximum corrosion resistance.

Temperature sensors ensure that power components will always operate within specified limits,if needed by automatic reduction of output current under extreme 

environmental conditions.

Universal 90-265V AC input voltage range and also suitable for DC supply(AC-DC and DC-DC operation)

All models will operate without any adjustment needed over a 90 to 265 Volt input voltage range,wheter 50Hz or 60Hz.

The chargers also accept a 90-400V DC supply.

Controlled charing

Every CHF charger has a microprocessor,which accurately controls the charging in three steps,The Charging process takes place in accordance 

with the IUoUo Characteristic and charges more rapidly than other processes.

To increase battery life: temperature compensation 

Every CHF charger comes with a battery temperature sensor,when connected,charge voltage will automatically decrease with increasing battery 

temperature,this feature is especially recommended for sealed batteries which otherwise might be overcharged and dry out due to wenting.

Battery voltage sense

In order to compensate for voltage loss due to cable resistance,CHF chargers are provided with a voltage sense facility so that the battery always

receive the correct charge voltage.

Two outputs to charge 2 battery banks

The CHF series chargers feature 2 isolated outputs.Each output is capable to supply the full reated current.
