Sifam Tinsley AP30-21JDZZZ000000 Alpha 30 Multifunction Meter

Sifam Tinsley, AP30-21JDZZZ000000, Alpha 30 Multifunction Meter, 0.2% Accuracy, 1 Phaze, 120V L-N 1/5A Input Voltage/Current, 12-48 V DC Power Supply, RS485

Features:

• On-site programmable PT/CT ratios: It is possible to program the primary of the potential external Transformer (PT), and the primary of the external Current Transformer (CT) on site via front panel keys by entering into Programming mode.
• User-selectable CT Secondary 5A / 1A: The secondary external Current Transformer (CT) can be programmed on-site to either 5A or 1A using front panel keys by entering into Programming mode.
• User-selectable PT Secondary: The secondary of the Potential external Transformer (PT) can be programmed on-site from 100VLL to 500VLL using front panel keys by entering into Programming mode.
• User selectable 3 phase 3Wire 4Wire or Single phase Network: User can program on site the network connection as either 3 Phase 3 Wire/4 Wire or single phase network using front panel keys by entering into Programming mode.
• Low back depth: The instrument has a very low back depth (behind the panel) of less than 80mm.
• Onsite selection of Auto scroll / Fixed Screen: Use can set the display in auto scrolling mode or fixed screen mode rising the front panel keys by entering into Programming mode.
• 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 & Export): Active Energy (kWh), Reactive Energy (kVArh), Apparent Energy (kVAh).
• True RMS measurement: The instrument measures distorted waveform up to the 15th Harmonic.
• High brightness 3 line 4 digits LED display: Simultaneous display of 3 Parameters.
• User selectable Low Current suppression (below 30 mA): The user can suppress the readings below 30 mA in the current measurement by onsite programming if required.
• Total Harmonic Distortion THD: The instrument can measure 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 1 min, the instrument updates the energy counter in the non-volatile memory. Programmable Energy format & Energy rollover count: The customer can assign the format for energy display on MODBUS (TtS-485) in terms of W, kW, or MW. Additionally to this, the customer can also set a rollover count from 7 to 14 digits (for W), 7 to 12 digits (for kW) & 7 to 9 digits (for MW), after which the energy will roll back to zero. The above settings are applicable to all types of energy.
• 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.
• Limit switch (Relay): The instrument will trip the relay if the programmed parameter exceeds the programmed Trip Limits.
• 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.
• A number of parameters measured, more than 46: The instrument measures more than 46  electrical parameters of 3 Phase network.
• Parameter Screen recall: In case of power failure, the instrument memorizes the last displayed screen. The displayed screen will get memorized only if the user keeps this screen for a minimum 40-sec duration before power failure for fixed screen mode.

Alpha 30 measures important electrical parameters like AC Voltage, AC Current, Frequency, Active, Reactive, Apparent Power, Import & Export Energy & many more.
