OVERVIEW

MODEL:

TPR3003T/TPR3005T

including both stable voltage and stable current function,

circuit protection, thermal protection with load ability etc

laboratory, electronics, communications equipment maintenance, Product line, scientific research

and teaching units. If power working long hours running state, overheating will shut off the output,

when machine temperature returned to normal, output power restore default state. The machine

has perfect protection function, can protect user equipment are not consumed.

INSTRUCTIONS

1. Note

(1) AC input

AC input should be 220V 10%, 50Hz

(If you are in the box 110V 10% 60Hz behind can indicate)

(2) Scattered heat

Do not exceed 40 degrees Celsius temperature environment in the local use, fan in the posterior

instrumentation, should have enough space, so scattered heat.

(3) Output voltage overshoot

When switching power supply device, the output voltage is not more than preset value.

(4) Overheating protection

This series of power is the perfect overheating protection function, can work under state

protection power will not lead to internal components overheating and burned power and user

equipment. If power transformer, internal temperature overheating will automatically cut off the

input voltage, When the internal temperature of power to the normal range, power will restore

default working state.

2. limiting Current Settings

(1)The decision to power instrument maximum safety.

(2)

Rotating voltage control knob, output voltage regulating 3V to 5V

Using a wire temporarily voltage output terminals (+) and (-) terminal circuit connection.

(3)

Rotating voltage control knob, until the CC designator light.

(4)

Adjust current knob to the current needs
