SINEAX DME 400 Programmable 3-Phase Transducer
The SINEAX DME 400 is a programmable 3-phase measuring transducer used to convert electrical quantities, voltage, current, active and reactive power, power factor, frequency, and energy, into stable analogue or digital signals for SCADA, BMS, and PLC systems. It is the unit Irish utilities, electrical engineers, and panel builders specify when they need accurate, repeatable measurement from a 3-phase network and a single device that can be programmed to output exactly the variables a downstream control system expects.
The DME 400 sits in the panel rather than on the bench. Once configured to your CT and VT ratios and the variables you want measured, it runs continuously in the background, feeding monitoring and control systems with measurement data they can act on.
What the SINEAX DME 400 measures
- 3-phase voltages and currents via direct connection or through CTs and VTs for higher ratings.
- Active, reactive, and apparent power across all three phases.
- Power factor per phase and system-level.
- Frequency with the accuracy needed for grid-connected applications.
- Energy values, with derived quantities depending on the configuration you order.
- Programmable variables, so you choose which measurements appear on which output channel and how they are scaled.
That programmability is what makes the SINEAX DME 400 different from a fixed-function meter. You configure the device once for the measurement range, output type, and signal scaling your control system requires, and the same hardware can cover dozens of different panel-mount applications across a site.
Why measurement accuracy matters in a transducer
A transducer sits upstream of every measurement decision a control system makes. If the device under-reads active power by a few percent, an energy management system will under-bill, an alarm threshold will trigger late, or a load-shedding scheme will misfire. The DME 400 is built for the kind of accuracy and long-term stability that makes those decisions trustworthy, in switchroom, panel, and industrial enclosure environments where temperature and electrical noise are realities.

FAQs
What is the difference between a transducer and a meter?
A meter typically displays values for a person to read. A transducer is designed to feed those values to another system as a stable analogue or digital signal. The SINEAX DME 400 is the second kind. It can replace several fixed-function meters with one programmable unit feeding SCADA, BMS, or PLC platforms.
Can the SINEAX DME 400 be programmed on site?
Yes. The DME 400 is a programmable transducer, so you set the measurement range, output type, and variables to suit the installation. Configuration is the part that gets the device matched to your CTs, VTs, and downstream control system.
Does the DME 400 need recalibration?
Yes, periodically. Long-term measurement accuracy depends on the device staying within calibration. Powerpoint Engineering’s calibration laboratory recalibrates SINEAX transducers and supplies a traceable certificate as part of the service.
