Installation and Operation

2.3.1 Power Input and Output Connection

2.3.1.1 POWERING THE MCP1631HV MULTI-CHEMISTRY BATTERY

CHARGER

1. Apply the input voltage to the input terminal block, J1. The input voltage source

should be limited to the 0V to +16V range. For nominal operation the input

voltage should be between +5.3V and +16V.

2. Connect the positive side of the input source (+) to pin 1 of J1. Connect the neg-

ative or return side (-) of the input source to pin 2 of J1. Refer to Figure 2-3 below.

FIGURE 2-3: Setup Configuration Diagram.

2.3.1.2 APPLYING A LOAD TO THE MCP1631HV MULTI-CHEMISTRY

BATTERY CHARGER

1. To apply a load (battery pack), to the MCP1631HV Multi-Chemistry Battery

Charger, the positive side of the battery pack (B+) should be connected to pin 1

of J2. The negative side of the load (B-) should be connected to pin 5 of J2.

2. For NiMH or NiCd battery packs, a thermistor referenced to (B-) in the battery

pack should be utilized. EPCOS Inc. PN B57500M0103A005 is the recom-

mended thermistor. If a thermistor is not available or not desired, a 10 k

Ω resistor

should be placed between pins 4 and 5 of the battery header (J2) or charger will

detect a missing thermistor and no charge cycle will begin.
