220v dc output power supply
Question-- Does all specification of the adjustable dc power supply with the same dimension ?
1.No , different specification with different dimension and different case
2.1000W 240*68*210 3.5k
3.2000W 253*68*268 4.5kg
4.3000-4000W 300*78*370 8.5kg
5.5000W-10KW 255*176*540 16.5kg
6.For more bigger power , the dimension and weight will base on the output voltage and current
Question-- Does the DC Power Supply support wide range input ?
1.No. our dc power supply design did not support wide range input
2.It is support input voltage as below
Single phase 110VAC+/-15%,Single phase 110VAC+/-20%,
Single phase 220VAC+/-15%,Single phase 220VAC+/-20%,
3 phase 380VAC+/-15%,3 phase 380VAC+/-20%
3 phase 415VAC+/-15%,3 phase 415VAC+/-20%
3 phase 450VAC+/-15%,3 phase 450VAC+/-20%
Question-- Does the external remote control port can design with DB9 Port ?
2.The external remote control port , we have DB9 Port and Terminal connection for option
Question-- For the external remote control Signal can control the output voltage only ?
2.Base on the request of user , our external remote control Signal can control the current and voltage in separate or simultaneously
3.We offer the 0-5vdc or 0-10vdc remote control Signal in usually
4.Other remote control Signal can be customize according to the customer request
Question-- What is difference between internal and external control signal?
1.The internal control signals is connected internal potentiometer with corresponding voltage and current signals in main board to adjust and control the output
2.The external control signal is supplied by two external 0-5V analog signal corresponding to the main board voltage and current signals to adjust and control the output
Question-- Can you customize the double channel output or the multi channels output?
1.For now, we Yucoo can only make the double output, and the unit price will be 150USD more than the same model that come put with one channel, and size will be also different.
2.Please come to the sales ask for more information.
Question-- Can you make the power supply with stable output?
Question-- Can you add PFC function?
The Yucoo power supply comes with the FC function.
Question-- If the end user CITY Power is 240VAC+/-15% but our power supply design is 220VAC+/-15%, does it still can working well ?
1.In usually , it still can working well
2.As our power supply support work at 240-250VAC all the time
3.But if the power more than 240-250VAC and running all the time , the power supply will be broken soon
4.The solution is add over or lower voltage protect function on the input of power supply
Question-- Does the power supply will be test in full load before shipping ?
2.The statement about all of our adjustable dc power supply have all been full load and 50% load were aging before shipping for 2-8 hours
3.If the power more than 3000w, the ageing time will be more longer , about 12-15hours
Question-- Does Positive and negative output can switch in auto or manual? If yes, what is the Switching interval time ? is it control by a switch or by time relay ?
1.It is control by time relay in auto
2.The buyer should be confirm to us before purchase for how long you want to switch
3.For example, if you want to switch Positive and negative output 1s. then we can set it before factory
Question-- Does the power supply can make EU power plug?
2.We can customize different type plug according to your request.
Question-- Can you make the input voltage as 70/80hz?
2.It can customize according to the customer request
