TPR3003T / TPR3005T and APS power difference:

1, TPR power for the LCD liquid crystal display, display current, voltage and power.

2, TPR power supply for the industrial power supply, reliability, stability, higher than the APS can be a long time, full of negative

APS is a civilian grade power supply.

3, TPR ripple and noise much smaller than the APS, for the high demand as much as possible to choose TPR series

4, TPR power supply fan noise is also smaller.

APS3005D is a single output high-precision DC power supply with output voltage and current constant within the rated current constant voltage constant current (CV / CC) automatic conversion mode, dual digital display head independent display output voltage and output current, A variety of protection features include current limiting buck, short circuit protection, over temperature protection, designed for factory production lines, maintenance, commissioning, laboratory and other places, is also essential equipment for the communications industry.

Constant voltage constant current CV / CC principle description
The device can be automatically converted in constant voltage constant current mode, its state depends on the load current and limited current value of the comparison results.
Constant voltage mode
When the current value is smaller than the set output limit current value, the power supply is operated in constant voltage mode. At this time, the constant voltage (CV) of the front panel is bright and the output voltage is controlled and the same value as the set value. Will vary with the load.
2. Constant current mode of operation (CC)
When the current value exceeds the output current limit, the device will operate in constant current mode, the constant current on the front panel red indicator ⑨ bright, the output current value is controlled at the set value, because the output power can not be overloaded, the output voltage will Will be lower than the set value below. When the output current is lower than the set value, the device will automatically switch to constant current working state.

Device power warning

● Input voltage AC220V ± 10%, 50Hz.
● The power cord should be reliably grounded to avoid electric shock.

Fuse warning
● Input voltage AC220V ± 10%, 50Hz
● The power cord should be reliably grounded to avoid electric shock.
● Fuse type: 3A / 250V
● Make sure the fuse is installed before starting the power supply.
● To prevent the occurrence of a fire, make sure that the replacement fuse is the specified specification.
● Disconnect the power cord before changing the fuse.
● Make sure that the fuse blows before replacing the fuse.

The equipment is clean
● Disconnect the power cord before cleaning the device.
● Clean the use of moist soft cloth with a mild detergent, do not use spray liquid to clean the equipment.
