SNG96 / ANG96 / ASM3-PV / MAR144 panel-mounted network analyzers 96×96 and 144×144 mm
Country: Spain · Model: SNG96 / ANG96 / ASM3-PV / MAR144
Four microprocessor-based panel analyzers of a three-phase network for flush mounting in DIN 96×96 mm cases (SNG96, ANG96, ASM3-PV) and a 144×144 mm case (MAR144) replace a set of ammeters, voltmeters and wattmeters with one programmable device. The group covers an entry level, a dedicated device for photovoltaic plants and an analyzer in an enlarged case.

Description
The SNG96, with a backlit LCD and a 5-button keypad, measures phase and line voltages, currents, and active and reactive power of a four-wire network by True RMS. It integrates maximum demand by current over a programmable time of 1–30 min, is powered from the measuring circuit and consumes less than 4 VA. The ANG96 accepts three current and three voltage signals, also works in a three-wire network with two or three CTs, and shows neutral current, power factor, frequency and maximum demand P, Q, S. The ASM3-PV has programmable 1 A/5 A inputs with a continuous overload of 2 In, calculates THD of voltage and current, meters imported and exported reactive energy and transmits data over RS485 Modbus-RTU. The MAR144, with three LED indicators, is made for single-phase, three-phase three-wire balanced or unbalanced and four-wire unbalanced networks and complies with EN 61010 class 2, category III. CE declarations have been issued for the SNG96, ANG96 and ASM3-PV.
How to choose
The model is determined by the network type and the interface needed. To replace pointer instruments on an incomer with x/5 A CTs the SNG96 or SNG96-C is enough, and an RJ45 connector with TCP/IP for a local network is available in the ANG96. At the output of solar plant inverters the ASM3-PV for 3×462/800 V AC is installed, and the MAR144 is chosen for single-phase schemes and where a large 144×144 mm case is needed. The AHM1 has an 8 MB data archive, and DC circuits up to 1500 V DC are monitored by the AR3DC / AR4DCT / TMCC.

FAQ
Can the ASM3-PV be connected to an inverter output without voltage transformers?
Yes, the device is rated for a nominal voltage of 3×462/800 V AC and direct measurement up to 1000 V phase-to-phase. Current is fed through 1 A or 5 A current transformers.
Does the SNG96 need a separate supply?
No, the SNG96 is powered from the measuring circuit and consumes less than 4 VA, so a separate auxiliary supply line is not needed in the board.
What is the RS485 communication speed in the SNG96-C?
The RS485 port is present in the SNG96-C version, and the communication speed is set within 1200–9600 baud.
Which networks is the MAR144 suitable for?
The MAR144 in a 144×144 mm case measures single-phase, three-phase three-wire and four-wire networks with a nominal voltage of 100, 110, 230 or 400 V and outputs data over Modbus RTU.
