Frequently Asked Questions

SD Series DC-DC Converters

1. Can the output voltage on the SD-1000L-48 be varied?

By means of an internal potentiometer the output voltage can be varied from 46 - 60 volts DC.

2. What is the switching frequency of the SD-1000L-series converter?

The SD-1000L-48 consists of a two-stage DC/DC converter. The first stage (Boost) has a switching frequency of 70 kHz. The second stage (isolation) has a switching frequency of 90 kHz. The two switching frequencies are different so that they don't superimpose emitting radiated and conducted EMI noise.
