SCR Controlled Loads: T Ambient operating temperature - 20 .. + 60 C A Acurate measurement of phase T Ambient storage temperature - 20 .. + 85 C S angle fired or burst fired (time m Mass 90 g proportioned) IPxx Protection degree IP20 SCRs. Current measurement gives faster response than temperature measurement. Switching Power Supplies and Electronic Ballasts: True RMS sensing is the most accurate way to measure power supply or ballast input power.
