Notes
1. Recommended input fusing is a 20 A HRC 200 V rated fuse. 2. Maximum is model dependent, Measured with external filter. See Application Note 190 for details. 3. Start-up into resistive load. 4. Maximum is model dependent, measured without external Pi filter. Significant reduction is possible with external filter. See Application Note 190 for details. 5. This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. 6. Negative remote ON/OFF option is available. Please add the suffix ‘-R’ to the part number, e.g. IBC30AQS4812-RAJ. 7. Output is rated at 450W constant power. Vin = 42 V: Imax = 42.9 A Vin = 48 V: Imax = 37.5 A Vin = 53 V: Imax = 34.0 A 8. ‘E’ option clearance is required to maintain ‘Basic’ creepage and clearance requirements when minimally insulated conductor paths are placed directly underneath the converter. 9. TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special request, please contact your local sales representative for details. 10. NOTICE: Some models do not support all options. Please contact your local Emerson Netwo.
