Frequently Asked Questions
What are the overall weight and slot capacities for the S3H3 and S3H5 models?
The S3H3 series is 6.0 lb. with 9 slots, while the S3H5 series weighs 9.0 lb. and can accommodate 14 slots.
What are the required components or procedures for adjusting output voltage settings?
Output voltage adjustment can be made using a user-adjustable potentiometer (pot) or via an I^2C interface, though factory set point accuracy is only guaranteed at 1%.
If I need to operate the unit in extreme temperatures, what derating calculation should I use?
The environmental specifications require you to derate each output by 2.5% for every degree rise above 50 °C, up to a maximum of 70 °C ambient temperature.
Is communication programming possible through the manual connections?
Yes, programming can be done via the USB Programming Connector; data transfer uses the I^2C Bus Output Connector (SDA and SCL signals).
