一年50万个出口以色列, 现寻工程师合作开发和加工厂,如下要求:
*100W,90Vac to 260Vac 输入,输出0~50Vac 可调
*RS232与电脑通信,电脑要显示电源的输出电流和电压
分两部份,电源部份和RS232软件部份,先开发电源部份,再开发软件部份。具体要求如下:
AC to AC adjust open frame power supply
Power rate:100W
Input voltage 90 volts to 260 volts 50 / 60 Hz. Output voltage changes from to 50 volts 50 /60 Hz Fully floating.
Pure sine wave, Synchronized to the input frequency
Unchanged at an angle Even changed of 0.1 % Not good.
**Change output voltage by potentiometer Its OK from 0 to 5 Vdc Linear. its control of 0Vac~50Vac output.
PCBA size:150mm*60mm*50mm, recommended 140x 60x60mm
2 wires for electricity standard to input and output Location does not matter this prototype.
LED indication for power on ,Overload and output short.
Now without LCD display for signal output voltage and signal output current now, but will make it be compatible for LCD display and RS232 in the furture when you require it.
Product need to meet UL standard
价格OK,我司马上付开发费。
请报单价?
