Product Description

Discription

1. Product Information

The constant voltage and constant current programmable control power supply module is cabinet and delicate, and it put the collection of analog integration and digital control functions in one. Its adjustable output voltage range is 0-32.0V, step by 0.1V. Its adjustable output current range is 0-3.10A, step by 0.01A. Boot voltages can be stored freely and the model has two groups of quick storage voltage. Compared with the traditional analog power supply, it is more convenient to quickly extract the voltage or current required. LCD display on the model has the function digital voltmeter and ammeter. You can view the preset voltage, input voltage, output voltage, the preset current, output current, output power and LCD brightness. The version with fan has a smart fan. When the output current is more than 1A, the fan will start working automatically.

2. Technical Parameters

1). Weight: 66g/piece(Host)+16g/piece(fan)

2). Dimension: 79mm*43mm*26mm (L*W*H)

3). Open size: 71mm*39mm

4). Input positive: IN+

5). Input negative: IN-

6). Output positive: OUT+

7). Output negative: OUT-

8). Output current: 0-3.10A (The max continuous working current is 2A without fan. Note: when you install the fan, please 9). refer the picture and note the direction of the fan.)

10). Output power: Maximum 99W

11). Input voltage range: 6-35V

12). Output voltage range: 0V-32.0V (In step down voltage mode, input voltage must be higher than 1V), the control button can fast draw up 2 sets data.

3. Display Introduction

U-IN: input voltage U-SET: preset voltage

U-OUT: output voltage I-SET: Preset current

I-OUT: output current POWER: output power

M-PRE: shortcut store B-LED: background brightness

M1: shortcut store1 M2: shortcut store 2

S-MD: setting the mode R-MD: normal operation

ON/0FF: open/shut down the module output

4. key Function Instruction

SET: Function setting, function confirmation;

ON/OFF: open or close voltage output.

m1: Shortcut extract M1 stored data/Upturning to choose/shortcut store.

m2: Shortcut extract M2 stored data/Page down to choose/shortcut store.

5. Operating Instructions

(1). Adjusting Preset Voltage

Pressing SET button, page down to U-SET, press the codding potentiometer, then enter toadjustnumeric value. Press codding potentiometer in turn to choose the numeric value you want to adjust. Turn codding potentiometer to adjust the numeric value. If you want toexit adjusting voltage, press shortly SET. In the process of adjusting preset voltage, if you open output voltage mode by pressing the ON/OFF, the output voltage will be refreshing by increasing or decreasing the numeric value; if you close output voltage mode by pressing the ON/OFF, the output voltage will not be refreshing by increasing or decreasing the numeric value.

(2). Adjusting Preset Current

Pressing SET button, page down to I-SET, press the codding potentiometer, then enter toadjustnumeric value. Press codding potentiometer in turn to choose the numeric value you want to adjust. Turn codding potentiometer to adjust the numeric value. If you want toexit adjusting current, press shortly SET.

(3). Power-Down Storage

If you want to use the present value includingthe preset voltage, the preset current, LCD brightnessat the next time of using the module, you should store those value. In the normal operating(R-MD), Keep pressing SET key until "MEMO" in red appears on LCD display, and then loose the key, indicating the preset voltage has been stored. You can use those value next time.

(4). Extract Shortcut Storage Value

When the system is the mode of setting mode( S-MD), Keep pressingm1orm2key, Shortcut storage valuecan be extracted.

(5). Store Shortcut Storage Value

Pressing SET button, page down to M-PRE, press the codding potentiometer, then enter the storage place of M1 or M2. In the meaning time, press shortlym1, the value would be stored in the place of M1; press shortlym2, the value would be stored in the place of M2.If you want to exit this mode, press shortly SET

(6). Adjusting Background Brightness

Pressing SET button, page down to the place of background brightness, press the codding potentiometer, then enter to adjust numeric value. Press codding potentiometer in turn to choose the numeric value you want to adjust. Turn codding potentiometer to adjust the numeric value.If you want to exit this mode, press shortly SET.

6. NOTE

When you do not use the module or adjust the preset voltage or current, the output will be advised to be closed in case of wrong operation of high voltage to burn the load.
The input voltage must be under 35v and 35v is the highest Voltage. Please leave adequate leeway,otherwise burn it.
When the input voltage cannot satisfy that the input voltage is higher the preset voltage about 1v, the module will automatically shut down output to prevent the module damage.
