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 Network

Power representative or use the on-line model number search tool at

http://www.powerconversion.com to find a suitable alternative.
