This paper will report on the flue gas CO-AF concentrations and minimal derating
potential, as well as observations on the operation of the ignition system, heat exchanger temperatures and discolorations indicative of high thermal stresses, and the high temperature limit control switches.
In both commercial and wireless applications, the built-in over-temperature protection and derating
function means there is no need for additional components to control heat.
The 4% derating
standard was based on work initially done in an altitude chamber by Eisman et al.
The curves do not have a 10% derating
and in fact the external trace chart is not conservative for what it actually represents.
If temperatures in a facility are chronically above this level, the UPS can still operate, but derating
may be required.
Configurable over-temperature derating
ensures predictable bulb operating life
175 % for 2 sec; ambient air temperature of 50AC without derating
(IP20); IP20 and IP66 protection; an integrated PI controller and V/F control with voltage boost.
The drive offers true side-by-side mounting without any derating
due to its compact, bookstyle design.
GENEVA, June 17 /PRNewswire-FirstCall/ -- STMicroelectronics , the market leader in thyristors and TRIACs, has introduced the first TRIACs with 10mA gate sensitivity to be specified for operation up to 150 degrees C without derating
, enabling low-cost solutions for heaters, motors and other small appliances, through savings in heatsinks, and gate-drive power-supply and snubber circuitry.
Now comes the piece de resistance: slew-rate derating
However, the unique protection gives effective heat transmission during a normal operating temperature, thus reducing the requirement for derating
TCJ Series capacitors maintain 20% recommended voltage derating
, extends usable voltage range
