Siemens releases entry-level power monitoring device for measuring energy.
The Sentron PAC3100 power monitoring device from the Siemens Industry Automation division records energy consumption and measures basic electrical values such as current, voltage, power, and frequency in low-voltage power distribution.
This new device in the Sentron PAC series is designed for the lower price range and it is the only device in its class with digital inputs and outputs and an integrated communications interface.
Easy installation and commissioning make the Sentron PAC3100 the ideal entry-level device for digital measurements in industry, non-residential buildings, and infrastructure. The monitoring device satisfies IEC61557-12, the new standard for power monitoring devices, along with its high requirements for operation characteristic and electrical safety, for example.
The Sentron PAC3100 seamlessly records the power and basic electrical values such as current, voltage, power, and frequency in three and four-wire networks. It can be directly connected in low voltage systems up to a rated voltage of 277VL-N /480VL-L. Higher voltages are measured using voltage transformers. Two energy meters measure the active and reactive energy, which can be set for supply, output, or balance respectively. The active energy is recorded with a measuring inaccuracy of less than 1%.
The new meter has a variety of certifications for worldwide use. Removable terminals, combined latching holder, and the overall depth of only 51 mm make it easy to install the compact device in 96x96 mm format. With its front in IP65 degree of protection, the product designed for panel mounting is also suitable for use in harsh environments.
The monitor is parameterised directly with just a few settings. This is done using four function keys and a large graphical liquid crystal display which also shows the measured values. Plain text displays in eight selectable languages support intuitive operator prompting. An RS485 communications interface with open Modbus RTU protocol transfers the measured values.
The power monitoring device has two digital inputs and two digital outputs as additional interfaces. The digital inputs with internal power supply can be used for status monitoring. They also allow relay contacts to be connected without their own power supply. The multifunctional digital outputs can be programmed as active or reactive energy pulses, or used as a switching output for telecontrol via Modbus RTU.
