Multimeeter M2 DC koos laengutasemega

The BLUE SEA SYSTEMS M2 DC multimeter with SoC (State of Charge) is a digital OLED monitor designed for precise energy management. It measures current, voltage, and battery state of charge. It is particularly useful for monitoring the full state of charge of a battery, the voltage of up to three battery banks, and the current of a bank.

The M2 DC multimeter with SoC precisely measures:

Voltage for up to three battery banks (with a resolution of 0.01V DC and an accuracy of ±1.0%).Current for one battery bank (with a range of -500A to 500A with the included shunt, and up to 5000A with external shunts).State of charge (SoC), capacity, remaining ampere-hours (Ah), and charge cycles for the main battery (Battery 1).

The M2 DC multimeter with SoC features a self-dimming OLED screen measuring 55 mm x 28 mm.

Yes, the front face of the M2 display is rated IP66, meaning it is protected against powerful water jets when installed according to the instructions. However, the rear of the unit is not waterproof and must not be exposed to water.

The M2 DC multimeter with SoC operates on an input voltage range of 7V to 70V DC.

The M2 multimeter is compatible with 12V, 24V, 36V, and 48V battery systems.

Yes, the M2 DC multimeter with SoC (model 1830) can measure the voltage of up to three battery banks and the current of one battery bank.

The M2 multimeter is equipped with 80 dB (or 92 dB depending on the source) audible alarms for the following thresholds:

High currentHigh/low voltageLow battery

Yes, the M2 multimeter includes an isolated 500 mA MOSFET relay. This relay can be used to activate external circuits based on configured alarm thresholds.

Yes, all M2 multimeter settings are stored in flash memory and retained even when the unit is powered off. Additionally, the SoC 1830 monitor logs the current charge state and charge cycle values every 15 minutes. Upon restart or power loss, it restores these values to their last saved state.

For standard installation, the M2 multimeter requires a mounting hole with a diameter of 2-1/8 inches (54 mm).

The M2 multimeter can be mounted on a panel with a maximum thickness of 1 inch (25 mm).

For accurate state-of-charge (SoC) monitoring with the 1830 model, the shunt must be connected between the negative terminal of battery 1 (house battery) and the main negative bus. All loads and charging sources must have their negative terminals connected to the main negative bus, except for the M2's negative source, which must be directly connected on the battery side of the shunt. The shunt's sensing wires must be a twisted pair.

Before starting installation, it is imperative to:

Disconnect the inverter’s power cables from the battery, if an inverter is installed.Stop and render any AC generator inoperative, if a generator is installed.Verify that no other DC or AC source is connected to the boat’s wiring.Ensure that battery 1 (house battery) is fully charged for the initial configuration.

The M2 multimeter's 8-pin connector supports wire sizes from 16 to 26 AWG. For shunt sensing wires, a twisted pair is recommended for accurate state-of-charge (SoC) calculation.

The M2 multimeter can be configured to monitor various battery types, including:

FLStd (Standard flooded lead-acid batteries)AGM (Standard AGM batteries)TPPL (Thin-plate pure lead AGM batteries)Gel (Gel batteries)FLRsv (Flooded lead-acid standby batteries)FLLoM (Sealed low-maintenance flooded lead-acid batteries)CFoam (Carbon foam AGM batteries)Lilon (Lithium-Ion batteries)

Yes, although the M2 multimeter is supplied with a 500A/50mV shunt, it can display up to +/- 5000A. This requires using a 5000A/50mV shunt, which is not included and must be purchased separately.

The M2 multimeter's power consumption ranges from 0.3W to 1.0W. This varies depending on supply voltage, display intensity, and standby mode.
