Battery Charger Of House Battery; Battery Low Voltage Protection; Voltage Charging Relay (Vcr) - Projecta INTELLI JAY PM100-BTJ Manual

1.2 Battery Charger of House Battery

The charger automatically starts when the power is connected, either from AC mains or generator.
With multiple charging stages (soft start, bulk, absorption, float, recycle), PM100J transformer is designed to fully charge
the battery quickly when connected to AC power. To guarantee the optimal charging for batteries of different states,
the transformer features a Microprocessor-controlled charging algorithm. The Float and Recycle charging program
guarantees that the battery condition does not change despite being connected for a longer period.

SOFT START
1
Increases battery life by gently starting to
charge the battery at 50% charge rate for
10 minutes if the battery is less than 11.5V
2 BULK
Reduces charging time by delivering
maximum charge to set voltage
POWER SUPPLY MODE
The PM100J transformer will automatically switch between power supply and charging modes, offering a static 12.8VDC
output for the DC loads.

1.3 Battery Low Voltage Protection

(BLVP, also known as an LVD)
The PM100J transformer has a built-in low voltage protection relay. It will disconnect the load once the battery voltage drop
below the threshold voltage. The default setting is 10.5VDC for lead acid batteries and 11.2VDC for lithium batteries.
1.4 Voltage Charging Relay
(VCR, also known as a VSR)
PM100-BTJ has a built-in voltage charging relay (VCR), which offers a convenient source to charge the house battery by
alternator whilst engine is running. When the vehicle battery reaches 13.4VDC (lead acid) or 13.7VDC (lithium) with threshold
time delay, the VCR will charge the house battery from the alternator. VCR will continue the charging until the vehicle battery
voltage drops under 12.8VDC (lead acid) or 13.3VDC (lithium).
NOTE: The PM100-BTJ when charging from the vehicle battery does not provide the 5 stage charge. It simply takes whatever
power and charging is available from the vehicle alternator.
