PROTECTION FUNCTIONS 

Over current protection

Yes

AC Input under voltage protection

When AC voltage <150Vac, the charger   will switch off

Output short circuit protection

Yes, will automatic resume after short is   removed

Battery reversed protection

yes

No-load   protection

yes

Over temperature

The charger must be able to operate up to   45℃ and will   de-rate the charge current linearly to 50% when reaching 60℃. When the   case reaching >65℃ the charger is allowed to stop, when the temperature falls, the   charger automatically resumes. No defects at high temperatures

Temperature compensation

For the lead-acid charger the NTC is used   for temperature compensation at -4mV/⁰C per 2V cell; 
  the length of NTC cable is 1 meter

For the Lithium charger the external   temperature sensor
  is used to prevent charging < 0 ℃ ambient temperature

Fan cooling

The Fan rotates at charging and stops after   fully charged

Fully charged automatic disconnect

Only for Lithium version by internal relay

Fault LED indication

Yes, see chapter LED indicators

USER ATTENTION 

·         Read these instructions and warnings before use.

·         The Charger must be used within Operating Ambient Temperature range -20~60℃ and humidity of < 90%

·         Do not place the charger outside, but always in a space that has some protection from outside weather influences

·         When the charger is installed, a minimum of 20 mm space all around the charger is needed.

·         Do not place the charger in a small not vented space; the charger will run hot.

·         The Charger must be yearly maintained, the air-flow slot which under the green plate must not be blocked, all dust and dirt substances must be cleaned. Check if the fan is operating properly during charging

·         Make sure the wires are placed in such a way that they cannot be damaged easily.

·         If the charger is used for electric vehicles like cars or boats, the interlock connection can be used to prevent the propulsion motor from starting during charge

·         The Lithium Battery must have a BMS protection with balancing the cells

·         The Lithium version of the charger will not charge below 0 ⁰C.

·         Place the NTC temperature sensor close to the battery

·         Never charge dead or damaged batteries

·         Do not attempt to disassemble the charger
