selects the battery type. There are two choices, Lithium Ion or Sealed Lead Acid (SLA) and

LiFE (Lithium Iron Phosphate). The Lithium setting is to be used with most NP-1 style Lithium

batteries. This is the factory default setting when we build and ship the PSC PowerStar Mini

Triple Play. In this setting, the volt meter will begin to blink on and off when the battery voltage

drops to approximately 13 Volts DC. This blinking meter function serves to warn the operator

that their battery and/or batteries are nearly fully discharged and should be replaced by fully

charged batteries at the earliest convenience. When the internal jumper is set to the SLA (or

LIFE) setting, the volt meter will begin blinking when the battery voltage drops to approximately

11 Volts DC. This setting is compatible with both SLA and LiFE batteries. Once again, if the

meter begins to blink on and off, the operator should also change out their batteries for fully

charged units.

TOTAL CURRENT EQUALS MAIN OUTPUT CURRENT + USB DC to DC INPUT CURRENT:

The USB 5Vdc voltage is supplied via a DC to DC converter. Therefore, the current draw from

your NP-1 or other source is less than the USB output current. This DC to DC converter

operates from 10 to 14 volts input and provides a 5 volts output. The output current and

voltage are inversely proportional to the input current and voltage. Here are some typical NP-1

battery current draws as they relate to the USB outputs:

USB Output Current NP-1 Current Draw

1 Amp 0.45 Amp

2 Amps 0.9 Amps

4 Amps 1.8 Amps

6 Amps (maximum USB Current) 2.7 Amps
