Sifam Tinsley, AP50-3JURZZ0000000, Alpha 50 Multifunction Meter, 3 Phaze, 120V Input Voltage/Current, 100-250 V AC/DC Power Supply, RS485
Features:
- Touchscreen graphics LCD: Alpha 50 has a touch sensible color graphics LCD display with a resolution of 320 x 240.
- On-site programmable PT/CT ratios: It is possible to program primary external potential Transformer (PT), primarily of external Current Transformer (CT) on site locally by entering into Programming mode.
- User selectable CT Secondary A/1A: The secondary external Current The transformer (CT) can be programmed on-site to either 5A or 1A locally by entering into Programming mode.
- User selectable PT Secondary: The secondary external potential The transformer (PT) can be programmed on-site locally by entering into Programming mode.
- User selectable 3 phase 3W or 4W unbalanced network: Users can program on-site the network connection as either 3 Phase 3 Wire or 4 Wire locally by entering into Programming mode.
- Low back depth: The instrument has a very low back depth (behind the panel) of less than 80 mm.
- Phase reversal indication: The instrument can detect the wrong phase sequence or failure of one of the input voltages and displays a "phase" error message.
- Energy measurement (Import and Export): Active energy (kWh), Reactive energy (kVArh), Apparent energy (kVAh) & Ampere Hour (kAh).
- True RMS measurement: The instrument measures distorted waveform up to the 15th Harmonic.
- User-selectable Low Current suppression (below 30 mA): Users can suppress readings below 30 mA in the current measurement by onsite programming if required.
- Phaser Diagram: Pictorial representation of all 3 Phases (Voltage & Current) in terms of vectors.
- Wave Form: Pictorial representation of all 3 phases of Current & voltage in terms of a sinusoidal waveform.
- Total Harmonic Distortion (THD): The instrument can measures per phase (%) THD of voltage and (%) THD of current.
- Energy Count storage: In case of power failure, the instrument memorizes the last energy count. Every 40 sec, the instrument updates the energy counter in the nonvolatile memory.
- Programmable Energy format & Energy rollover count: Customers can assign the format for energy display on MODBUS (RS-485) in terms of W, kW, or MW. Additional to this, customers can also set a rollover count from 7 to 14 digits depending on the energy format.
- Hour Run, ON Hour, Number of Interruptions: Hour run records the number of hours the load is connected. ON Hour is the period for which the auxiliary supply is ON. The number of Interruptions indicates the number of times the Auxiliary Supply was interrupted.
- Min Max storage of parameters possible: The instrument stores minimum and maximum values for System Voltage and System Current. Every 40-sec minimum and maximum readings are updated
Alpha 50 measures important electrical parameters in 3-phase and single-phase networks & replaces the multiple analog panel meters. It measures electrical parameters like AC current, Voltage, frequency, active energy import & active energy export, Current Demand, kW Demand, kVA Demand, and Max Current Demand, Max kW Demand, and Max kVA Demand.
