Description
4 specifications for you to choose
PLEASE NOTE:
1. Due to the design of the power supply, the front panel is only suitable for output currents up to 5A. To avoid damaging the power supply or load and output more accurately, connect the high current connector on the back of the unit for output currents above 5A. The back panel can reach the maximum current of the purchased specification: for example, if you purchase 30V 30A, the current can reach 30A by connecting the back panel high-current terminal
2. New Function Output Switch: You can set the current directly without "short circuit"! Sometimes we need to switch between different voltage or current outputs, but often we forget to unplug the previous instrument, causing it to burn out, a situation that often occurs in maintenance. The output on/off key is designed to solve this problem, press the output on/off key to adjust the required voltage and current, which makes this DC power supply more secure
3. Upgrade High-precision Encoder Knob: Just "set" voltage and current instead of "adjust". The encoder switch replaces the potentiometer switch, the digits are switched by pressing the knob and each digit can be set in the range 0-9 by turning the knob. Makes work easier and more efficient
4. Stable Output, Auto Switch C.C/C.V Mode: This variable DC power supply is a low noise, low ripple adjustable high power continuous output power supply that can work at full load for long periods of time. Constant voltage and constant current modes can be switched automatically
5. 4-Digit LED Display, Power Display: 15V 60A DC Power Supply is a professional power conditioning unit with high resolution of 0.01V and 0.001A. The backlit 4-digit LED display of the bench power supply shows the voltage current and power values more accurately and is easy to see even in low light conditions
6. Multiple Protection, Intelligent Cooling Fan, Reliable and Safe: The DC power supply has built-in overvoltage protection, overcurrent protection, overheating protection and termination protection. When the operating temperature of the DC power supply exceeds 122°F/50°C, the fan will turn on intelligently to dissipate heat effectively and extend the life of the device. DC power supply has shock absorbing rubber feet at the bottom for safer and more stable use
7. CE & FCC Certification, Widely Used:15v 60a Lab power supplies have passed CE & FCC Certification. This benchtop power supply is suitable for battery charging ( LiFePO4, lead acid batteries, etc.), labs, schools, electronics repair, electrolysis, electroplating, lamp testing, aging testing, DIY, research and teaching
8. Compact Design, Quality Check: The bench power supply measures only 38*24*13cm and weighs only 3kg, saving you more bench space and making it easy to carry around when you need it. Delivery includes: DC power supply *1; power cord *1; English manual; low-power output cable *1; high-power output cable *1. We offer a 12-month repair policy. If you have any questions about our lab DC power supplies, please contact us and we will reply within 24 hours

SAFETY BRIEF
This manual contains important safety instructions that must be followed in the operation and storage environment of the R-SPS series.To ensure your personal safety, and ensures that this product works in the best environment, please read this manual carefully before using .
When you get a brand-new power supply, you need to do then ecessary checks to make sure the instrument is working properly.
1. To check whether there are damages caused during transportation.
2. To check whether all the accessories are complete.
3. To check whether the output voltage and output current are normal after turning on the device.
lf finding out any problems, please contact the merchant immediately.
SAFETY SYMBOL
The safety symbols below will appear in this manual or on theDC power supply.
PRODUCT BRIEF
The R-SPs series of adjustable regulated DC Power Supplydesigned for use in laboratories,schools and production lines.Both output voltage and output current are continuously adjustablebetween 0 and nominal.
The stability and ripple factor of the power supply are very goodand have a perfect protection circuit. Can work at full load for along time.This power supply can be used as both a regulatedpower supply and a regulated current supply.
The above parameters are measured at an ambient temperature of 25±5C, relative humidity: <80%RH, andpreheated for 30 minutes.The actual parameters will varyslightly.
WORK REQUIEMENT
1.AC input: Please make sure the input voltage of this product
230V10%50Hz 115 V10%60Hz
2.Do not use in an environment where the ambient temperatureexceeds 40 degrees Celsius.The cooling fan is located at therear of the device and should have enough space for cooling.
Warning:
lncorrect AC voltage input will cause serious damage to the device.Please make sure the required input voltage value.
OPERATION INSTRUCTION
There are two types of power output modes: constant voltageoutput (CV) and constant current output (CC).The output modeis determined by the voltage and current values set by the userand the load connected by the user.The output voltage or current value of the power supply won't exceed the voltage andcurrent values set by the user. ln constant voltage mode, theoutput voltage value is equal to the user-set voltage value. Inconstant current mode, the output current value is equal to theuser-set current value.
For example: the voltage value is set to 5V and the current valueis set to 5A.
Steps
1. Turn on the powe switch
2. Adjust the voltage adjustment knob to 5V
3. Connect the “positive” and “negative" with wires and adjustthe current knob to 5A.
4. Disconnect the wire and connect the load to use.
Attention：
ln actual CV operation, if the load resistance decreases and theoutput current increases to the set current value, the power supplywill automatically switch to cC mode. When the load resistancevalue continues to decrease, the current will remain at the currentset value.The voltage is proportionally reduced.At this time, increase the load resistance or increase the current set value torestore the CV output state.
CONNECT THE LOAD
1. Rotate the terminal knob by turning it counterclockwise
2. Insert the load terminal
3. Turn the terminal knob clockwise
4. Banana plug can be directly inserted into the terminal hole
Attention：
lmproper connection may result in damage to the powersupply and the load connected to the power supply. Whenconnecting the battery load, do not reverse the polarity ofthe "+" and"-" as this may damage the power supply.
CONSTANT VOLTAGE/ CONSTANT CURRENTCHARACTERISTICS
The working characteristics of this series of power supplies areconstant voltage/constant current automatic conversion type,which can automatically change between constant voltage andconstant current states with load changes.The intersectionbetween constant voltage and constant current mode is calledconversion point.For example, if the load causes the power supply to operate in a constant voltage mode, a constant voltageis output.As the load increases, the output voltage will remainconstant and the output current will increase. When the currentvalue reaches the set current limit value, the power supply willautomatically switch to constant current mode.The outputcurrent remains stable and the output voltage decreases proportionally as the load increases further.The conversion ofconstant voltage and constant current is indicated by the LED onthe front panel.
CV indicator light is on during constant voltage, cC indicator ison when constant current.
FUSE REPLACEMENT：
lf the fuse blows, the power supply will stop working.To find andcorrect the cause of the blown fuse, then replace it with a fuse ofthe same specification.
HIGH VOLTAGE!
DANGER!
For effective safety protection, it is only necessary toreplace the fuse of a specific specification.Before replacing the fuse,the power must be turned off and thepower cord must be unplugged from the power outlet.
