Product Upgrade Notice: CSP-3000 Optimization and Conformal Coating Added

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
   With adding LED Signal function, users can quickly determine whether the power supply is working normally or not for troubleshooting.
5. Adding Conformal Coating
   As most CSP-3000 models are applied in a dusty and humid environment from customers’ feedbacks, conformal coating is added to standard products. (Fig.5)
