Description

The Senva EM-RS485 is the safest and fastest meter to install on the market. It is the perfect product for retrofits as the high voltage components are embedded in the Current/Voltage Transducer™ (CVT™). The entire assembly is easily mounted inside the electrical panel, eliminating labor and space required to install a separate transducer box. Each CVT™ sensor uses digital communication with the meter for superior noise immunity – ideal for applications where accuracy matters! The CVT™ sensors are individually calibrated and measurement accuracy is independent of the transducer.

The EM-RS485 is a three channel meter, capable of monitoring single-phase, two-phase and three-phase systems, as well as 3 independent single-phase systems with one meter. The EM-RS485 meter offers BACnet MS/TP and Modbus RTU protocols and 2 pulse inputs to maintain flexibility during installation and operation. The EM-RS485 is compatible with all sizes of CVT’s™. With the EM-RS485 intelligent meter technology, the device self-configures baud rate, serial format, protocol, and address (BACnet only) – eliminating additional configuration steps. One universal EM-RS485 meter supports all CVT™ sensor options (sold separately) in the family.

Features:

• 0.2% Meter Accuracy (ANSI C12.20 Class 0.2 standards), 1% System (meter + CVT™) Accuracy
• Auto-configures baud rate, network type, serial format and self-addresses – No manual configuration necessary during install
• Supports both BACnet MS/TP and Modbus RTU
• Self diagnosing meter for troubleshooting assistance
• 2 pulse inputs for connecting other meters (water, gas, steam, etc.)
• One universal meter supports all CVT™ sensor options (sold separately) in the family
• All CVT’s™ (sold separately) sizes rated for 90-600V
• Calibration is at the CVT™ level so any CVT™ from the family will maintain its accuracy with any EM Series meter
• Multiple mounting options
• Supports mounting on either horizontal or vertical PR30 (TS 35/F6) DIN rail
• Snap-in mounting ears allow screwing to any suitable surface
• Integrated rare earth magenets secures the EM-RS485 meter to any ferrous enclosure or surface – ideal for auditing!
• Compact Size – fits in the palm of your hand!
