Panel Mount Meter for 3-Phase Network Parameters, LED Display, 96 x 96mm

The ND04 from LUMEL is a panel mounted 96 x 96mm DIN quadratic digital panel meter for the measurement of important electrical parameters like AC voltage, AC current, RPM, frequency.

The instrument integrates accurate measurement technology (all Voltages & current measurements are True RMS up to 15th harmonic) with a 3-line 4-digits ultra high bright LED display with clearly visible annunciated units with bright LEDs from the back side.

Delta can be configured and programmed on site for the following: PT primary, PT secondary, CT primary, CT secondary (5A or 1A) and system type 3-phase 3-wire or 4-wire.

The front panel has four push buttons for the user interface to scroll through the available parameters.

Measured parameters, available on the display:

current I, I₁, I₂, I₃, voltage U, U₁, U₂, U₃, U₁₂, U₂₃, U₃₁, frequency f
worktime, hour run, number of interruptions, rotation speed of generator

Technical data:

Input voltage:

Nominal input voltage (AC, RMS): Phase-Neutral 290V, Phase-Phase 500V
System PT secondary values: 100V (L-L) to 500V (L-L), programmable on site
System PT primary values: 100V (L-L) to 692kV (L-L), programmable on site
Max continuous input voltage: 120 % of rated value
Nominal input voltage burden: < 0.3 VA approx. per phase (for external auxiliary meter)

Input current:

Nominal input current: 5AAC RMS
System CT secondary values: 1A/5A (programmable on site.)
System CT primary values: from 1A up to 9999A
Max continuous input current: 120% of rated value
Nominal input current burden: < 0.2VA approx. per phase

Accuracy:

Voltage: ±1% of range (for 20...100% of nominal value)
Current: ±1% of range (for 10...100% of nominal value)
Frequency: ± 0.5% of mid frequency

Auxiliary supply:

External Aux: 40V - 300V AC/DC. (±5 %), 45 to 65 Hz or 12 - 48V DC (please specify when ordering)
Self powered: input voltage range from 80% to 100% of rated value, 45 to 65 Hz (self powered meter is available only in 3 Phase 4 wire network. Auxiliary input is derived from phase 1)
VA burden: < 3 VA
