MEAN WELL CSP-3000 - Optimization and Conformal Coating Added
CSP-3000 is MEAN WELL first high-voltage power supply, providing 120V / 250V / 400V output voltage. Since it was launched, it has been highly favored and being widely used in laser, UV curing and charging applications. In order to make the product fit to the market application better, several upgrades from customers’ feedbacks are made, listed as follow：
1. Adjusting PV/PC Function
The original access to external voltage signal of PV/PC is 20%~100%, 8%~100% for PWM. After optimization, the external voltage and PWM signal controllable range are uniformly defined (show as Fig. 1), and the PV range is 15% to 100%, PC range is 8% ~ 100%.
2. Adding PV/PC Adjustment Method
PV/PC can be adjusted via two methods, one is external voltage 10V, and the other is 500~1KHz PWM signal, enhancing the adjustment flexibility. (show as Fig. 2)
3. Canceling Rapid Output Response
CN2 PIN5/PIN6 functions were rapid output response. However, considering the speed of 500Hz~1KHz is not fast enough for certain applications, rapid output response is removed after the optimization (Fig.3). CN2 PIN5/PIN6 are for PV/PC function and NC PIN for PIN7/PIN8.
4. Adding LED Signal
5. Adding Conformal Coating
