User Manual

Models PS1001, PS1002, & PS1005 USB output can provide

stable 5V DC voltage power. The maximum current is 1000mA

(PS1003 & PS1004 maximum current is 2.1A).

NOTE: Before using the USB power supply, make sure the

device can be charged by USB and the maximum working

current is no more than 1000mA (PS1003 & PS1004

maximum working current is no more than 2.1A)

HOW TO USE THE USB POWER SUPPLY

Battery operating time depends on battery capacity (AH) and

load power (W), the calculation formula of operating time is:

battery capacity (AH) x battery output voltage (V) ÷ load

power (W)

For example: Battery specification: 12V 200Ah, load power is

300W, then the operating time is 200 x 12 ÷ 300≈8 hours

BATTERY OPERATING TIME

This unit uses the latest in soft start technology. The output

voltage gradually increases to the normal value from low

value after the inverter is turned on. It can reduce the tran-

sient large current attack and help to start the hard start load.

Large power inductive load, such as electrical motor or capac-

itive loads (large power SMPS), adopt soft start. Turn on the

“load switch”, then turn on the “inverter switch.”
