PV- 5127: Power supply module with UPS

Installation guide

Precautions to ESD

Please note that the Micronix PV modules must be handled with respect to ESD (Electrostatic Discharge). Electrostatic Discharge to the PV modules must be avoided.

Before removing the module from the protection bag, the user must be discharged using a grounded wrist ribbon.

Settings and connections

ST1

To set the fast charge current to 1A, install a jumper at ST1 (factory default). To set the fast charge current to 0.5A, remove jumper at ST1.

J1

Connect an external temperature sensor at J1 (i.e. PV-5127-TW40) if the battery temperature is to be supervised during the charging process. The battery temperature control can be disabled by installing a jumper at J1 (factory default). Leave ST1 unconnected when PV-5127 is used with a PV-1075 battery module. See section Connectors and Battery monitor and charger.

ST3

Connect a jumper in position ‘On-board sensor’ if the system temperature is to be measured by the on-board sensor. If the system temperature is to be measured by an external sensor, leave ST3 unconnected. To disable the system temperature control, install a jumper in the position ‘10°C’ (factory default).

J2

Connect an external temperature sensor at J2 (i.e. PV-5127-TW40) if the system temperature is to be supervised by an external sensor. Otherwise leave J2 unconnected. See section Connectors and System temperature.

CN2

If external LED indicators or the heater and fan control outputs are used, connect these through CN2. Otherwise leave CN2 unconnected. See section Connectors.

CN3

If the ‘simple signalling’ protocol is to be used for the UPS control, connect a suitable cable (i.e. CDB-9F) between CN3 and a COM port on the CPU. Otherwise leave CN3 unconnected. See section UPS Control.

CN10

If your CPU has a 5V Standby power input and a PS_ON output, connect them to the corresponding pins in CN10 (ATX). Otherwise place a jumper on the two leftmost pins in CN10 to permanently activate PS_ON (factory default). See section Connectors and section UPS Control.
