Thanks for using our products, please read this manual thoroughly before
operation.
MODEL:
regulated DC power supply is a high reliability,
including both stable voltage and stable current function,
TPR3003T/TPR3005T
Restricted current lower voltage, short
circuit protection, thermal protection with load ability etc
The power supply is suitable for the
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

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