Notes & safety
Notes: 1. This product is not designed for use in critical life support systems, equipment used in hazardous environments, nuclear control systems, or other such applications which necessitate specific safety and regulatory standards other than the ones listed in this datasheet.
2. Ripple & Noise are measured at 20MHz bandwidth with a 0.1uF & 47uF parallel capacitor
3. Natural convection is about 20LFM but is not equal to still air (0 LFM)
4. Safety Approvals cover frequency 47-63Hz.
5. It is recommended to add Varistor 14S471K at L/N input side in parallel.
6. In order to indicate Screw Terminal option, add –A to model number. Ex. PSCZM20-12S-A
*Due to advances in technology, specifications subject to change without notice.
