DSM-PWR
Description: The DSM-PWR is a fully programmable, Native BACnet™ Building Controller designed as an interface to the Delta Controls Power Meter. The DSM-PWR acts as a gateway, translating information from the power meter into BACnet objects that reside in the gateway controller, which can then be accessed by the rest of the BACnet network.
Features:
- Native BACnet firmware
- Energy management and performance contracting
- Activity based costing in commercial and industrial facilities
- Monitor kW, kWh, kVAR, kVA, PF, Amps and Volts
- Fast split-core installation eliminates the need to remove conductors
- Precision metering electronics and current transformers in a single package
- Smart electronics eliminate current transformer orientation issues
- High system accuracy (±1%) conforms to ANSI C12.1 metering standards
- 8 button keypad with LCD
- Fully programmable in GCL+
- Database and Firmware can be loaded over the network
- Real-time clock
- Battery backup
- Service port
Application: The DSM-PWR uses three-phase, networked (Modbus RTU) power meters for energy service metering and submetering in both commercial and industrial applications. These innovative meters combine power metering electronics, and high accuracy industrial grade current transformers in a single package eliminating the need for external enclosures.
The power meters output 26 energy variables including kVAR, VA, and power factor which makes them ideal for power monitoring and diagnostics.
The DSM-PWR comes loaded with the Modbus Gateway and a specialized database that utilizes the DSM-PWR’s LCD and keypad as a stand alone interface to monitor energy parameters.
