Description

1-PHASE POWER NETWORK METER

The N30P meter is a programmable digital panel meter destined for the measurement of a.c. voltage, a.c. current, active, reactive and apparent power, cos ϕ, tg ϕ, ϕ, frequency, active, reactive and apparent energy, 15, 30 and 60 minutes’ active power, 10 minutes’ voltage, 10 seconds’ frequency.

Additionally, the meter enables the indication of the current time. The readout field is composed of a display which allows to expose results in red, green and orange colours.

Features of the N30P meter:

• display colour individually in three ranges,

• thresholds of displayed overflows,

• 2 NOC relay alarms operating in 6 modes,

• 2 switched relay alarms operating in 6 modes (option),

• signaling of measuring range overflow,

• automatic setting of the decimal point,

• programming of voltage and current ratios,

• programming of alarm and analog outputs with the reaction on any

measured value, independently of the currently displayed value,

• storage of maximal and minimal values of all input quantities,

• reset of all watt-hour meters: active and reactive energy,

• programmed kind of 15, 30 or 60 minutes’ active power measurement:

mean walking or synchronization with the RTC clock,

• manual synchronization of 15 minutes” power, 10 minutes’ voltage,

• monitoring of set parameter values,

• interlocking of parameter introduction by means of a password,

• service of the interface with MODBUS protocol in the

RTU mode (option),

• updating of software through interface RS485,

• conversion of the measured value into a standard – programmable

current or voltage signal (option),

The set is composed of:

– N30P meter…………………………………… 1 pc

– User’s manual……………………………….. 1 pc

– Guarantee card……………………………… 1 pc

– Clamps to fix in the panel……………….. 4 pcs
