APS3005DM (Baekje), non-Aetna letter brand, mind, please carefully shot.

This model current is4-bit mA display , Please note when buying

APS3005DM: 0 ~ 30V 0 ~ 5A adjustable

TPR3003T / TPR3005T and APS power difference:

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

2, TPR power supply for industrial power, reliability, stability than the APS is high. Can be a long time, full negative

APS is a civil grade power supply.

3, TPR ripple and noise much smaller than the APS, TPR series as much as possible for the choice of high

4, TPR power supply fan noise should be smaller.

APS3005D is a single output high-precision DC power supply, with the output voltage and current within the rated continuous adjustable constant voltage constant current (CV / CC) automatic conversion mode, dual digital display independent display output voltage and output current, A variety of protection features, including 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.

2. Power cord

Constant Voltage Constant Current CV / CC Principle Description
The device can be in constant voltage constant current mode of operation automatically switches, and its state is determined by the load current and the comparison of the current value of the results.
Constant voltage mode CV
When the current value is less than the set output current limit, the power supply is in constant voltage mode. When the constant voltage (CV) green LED on the front panel is on, the output voltage will be controlled and the current will be the same. Will change with the load changes.
2. Constant current operating mode (CC)
When the current value exceeds the output current limit, the device will work in constant current mode, the front panel constant current red indicator ⑨ light, the output current value is controlled at the set value, due to limit the output power can not overload, the output voltage 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 properly grounded to avoid electrical shock.

Fuse warning
● Input voltage AC220V ± 10%, 50Hz
● The power cord should be properly grounded to avoid electrical shock.
● Fuse type: 3A / 250V
• Verify that the fuses are installed before starting up the power supply.
● To prevent a fire, ensure that the replacement fuse is a specified size.
● Disconnect the power cord before changing the fuse.
● Check the cause of blown fuse before replacing the fuse.

The equipment is clean
● Disconnect the power cord before cleaning.
● When cleaning, use a soft, soft cloth with a mild detergent. Do not use spray liquid to clean the device.
● Do not use chemical solvents and irritating cleaners such as benzene, toluene, xylene, acetone and so on.
