8.2.1 Design Requirements

Figure 15 is the typical application for the AFE3010 when the SEL pin is grounded. The system requirements shown in Table 4 are based upon the UL-943 standard. The required component power and voltage ratings should be chosen based upon the line voltage. See Table 5 for more information on power ratings.

Table 4. Design Requirements

DESIGN PARAMETER VALUE
Line or source voltage 120 VAC (±15%)
Line frequency 50-60 Hz
Line polarity (connection to GFCI unit) Normal and reverse polarity
Operational temperature –40 °C to +105 °C
Rated load 20 A RMS
Ground fault threshold (trip point) 5 mA RMS
Ground fault threshold variation over all parameters ±0.5 mA RMS
Neutral-to-ground fault detection Per UL-943
