2: IQ 150S/250S Submeter Overview and Specifications
2.1: Hardware Overview
Eaton’s IQ 150S/250S submeter is designed to measure
revenue grade electrical energy usage and communicate
that information via various communication media. The unit
supports RS485, RJ45 wired Ethernet or IEEE 802.11 WiFi
Ethernet connections. This allows the submeter to be
placed anywhere within an industrial or commercial facility
and still communicate quickly and easily back to central
software.
The unit is designed with advanced measurement
capabilities, allowing it to achieve high performance
accuracy. The IQ 150S meter is specified as a 0.2% class
energy meter for billing applications (the IQ 250S is so
specified for Class 10 only). To verify the submeter’s perfor-
mance and calibration, power providers use field test stan-
dards to verify that the unit’s energy measurements are correct. The IQ 150S/250S meter is a
traceable revenue meter and contains a utility grade test pulse to verify rated accuracy.
The IQ 250S meter has up to 2 MegaBytes* for datalogging. It offers three
historical logs, a Limits (Alarm) log, and a System Events log.
*NOTE
: Because the memory is flash-based rather than NVRAM (non-volatile
random-access memory), some sectors are reserved for overhead, erase procedures, and spare
sectors for long-term wear reduction.
