GENERAL DESCRIPTION

The ADSST-SALEM-3T energy meter chipset consists of an efficient ADSST-218x digital signal processor (DSP), a fast and accurate 6-channel, 16-bit ADSST-73360LAR sigma-delta ana-log-to-digital converter (ADC), and metering software. Two chipset versions are available to support differing ranges of operating temperature: The ADSST-EM-3040 chipset is rated at 0°C to 70°C for commercial applications, while the ADSST-EM-3041 chipset operates at –25°C to +85°C for industrial use.
