YIHUA 605D DC Power Supply
YH-605D communication maintenance power supply
605D communication maintenance power supply is a single line output of stabilized high accuracy
DC stabilized power supply. The output voltage and current can be adjusted continuously within
the rated range. Double digital display shows output voltage and current independently. Several
protection functions include current limitation, voltage reduction, short circuit protection, over-
temperature protection, etc.
The design is applied to production line of the plant, maintenance, laboratories and is also
a necessary device for the communication industry.

Principle description of constant voltage/constant current CV/CC
The operation mode of constant voltage/constant current can be automatically switched depending
on the comparison result of the load current and limited current value.
- a) Constant voltage CV
When the existing current value is smaller than the set output limit current value, the power supply
is working under the constant voltage mode. The CV indicator light on the front panel is on, the output
voltage is controlled and it will be the same as the set value. Current changes with the load.
- b) Constant current mode (CC)
When the current value exceeds the limit value of the output current, the equipment will work in the
CC mode. The CC indicator light on the front panel is on, the output current value is controlled to
the set value. Since the limited output power cannot be overloaded, the output voltage can be lower
than the set value. When the output current is lower than the set value, the equipment will
automatically change to CC mode.

Clamp Meters
UT256B ACA DCA Fork Clamp Meters
UT256 series is an AC/DC fork meter with high reliability, high security, auto-range, and mini shape. Its appearance adopts creative design so that wires to be tested can be stuck by the jaw directly instead of after the jaw is pressed to open. It can measure AC/DC current provided with true RMS function. Flashlight on the meter is specially designed for smooth measurement under darkness. Full-range overload protection and distinctive appearance design make it be a new-generation practical electrical measuring meter with better performance.
