Description

Technology

The Centaur Charger is a fully high-frequency switched battery charger. The input is electronically power factor corrected by the first power stage.
The next stage gives provision for galvanic isolation and a perfect DC voltage at the output terminals.
The internal electronic parts are protected against moisture and dirt by means of a special coating, which assures a long lifetime of your battery charger.
Three high-capacity batteries can be charged simultaneously with this charger.

Operation

The battery charger charges the battery with 3-stage (BulkAbsorption-Float) charging characteristic.
It can remain connected to the battery continuously, without increased gas formation, caused by overcharging, taking place.
The charger can be used for different types of batteries but the default settings are for Gel batteries.
For use with other types of batteries please select Lead-acid or AGM by opening front bottom cover and select DIP switch in bottom left-hand corner. See Figure 1.
The full charging current of this Charger is divided in three main outputs but anyone output can supply 100% of power if that is the only battery connected.

TROUBLESHOOTING
Problem Possible cause Solution
Charger does not function The mains is not ok Measure mains
Input or output fuses are defective Return product to your dealer
The battery does not get fully  charged A bad battery connection Check

battery connection
 The battery select switch is in the wrong setting| Select correct battery type (see Fig1)
Battery capacity to large| Make sure charger capacity matches battery
The battery is being overcharged| The battery select switch is in the wrong setting| Select correct  battery type (see Fig1)
A single cell in battery is defective| Replace battery
Too small battery| Consult your battery supplier

Installation

WARNING: Qualified personnel only

Instructions
  1. Mount wall bracket (for top holding) of the battery charger, make sure it is level.
  2. Install three screws.
  3. Open cover by removing four screws, on front bottom cover.
  4. Put charger on mounting bracket and mark the Bottom of the two (M6-D-holes) mounting holes.
  5. Install M6 screws.
  6. Install AC cord to input terminal strip marked E, N, L, be sure to use the correct size wire (per ABYC regulations) to use for the input current marked on the label of charger.
  7. Cut DC inlet plugs to cable size, then connect battery cables to DC lugs marked +DC & -DC. The -DC is used commonly for all three batteries. If there are less than three batteries, pick any +DC; all are capable of full current load. Select appropriate size wire (per ABYC regulations).
  8. Select battery type by pushing the appropriate DIP switch at bottom left corner of board. Note: This unit is selected for GEL; if you change battery type DESELECT GEL, (See Figure 1).
  9. Replace top cover and reinstall four screws on cover.
  10. Apply power and verify Green LED is on (bottom left of PC board, look through bottom left air vents).

Location

The Centaur Charger must be installed in a dry, well-ventilated area.
Too high an ambient temperature has the consequence of lower output, shorter life or a complete shutdown of the Centaur Charger.
The Centaur Charger is suitable for floor and wall mounting.
However, for optimum cooling, a vertical position is recommended.
The cables between the Centaur Charger and the battery must be kept as short as possible to minimize cable losses. Input/output connections refer to Figure

24/60| 120| 15| 240| 9

Note:

For other input voltages Uin the input current can be calculated as follows:
Input current = (current at 120Vac) x (120 / Uin)

Example:
Input current at 120Vac: 3,35 Amps
Required: input current at Uin = 110Vac
Answer: input current = 3,35 x (120 / 110) = 3,65A
