POWER MEASUREMENT WHERE AND HOW YOU WANT THEM

WHERE: Installation in modular panel.
HOW: The measurements give a full view of electrical consumption including storage of power peaks and consumption (Maximum demand of Active Power).
High accuracy (class 1 IEC1036).
Voltage input: Max. direct 550V or from 2 or 3 voltage transformers: primary value programmable from 1V to 999999V; secondary value selection from 57.7, 63.5, 100, 115, 120, 173, 190, 200, 220 Volt configuration.
Current input: Direct 5A or through secondary of CT/5 or CT/2.5, CT/2, CT/1. Primary value of CT selectable from 1 to 999999 A). Accepts alternatively either 2 or 3 CTs.
All the models are available with 30A current input.
Automatic scale change.
Average KVA: integration times of 1', 2', 5', 10', 15', 20', 30', 60'.
Average KW: integration times of 1', 2', 5', 10', 15', 20', 30', 60'.
Ampere Crest Factor (1/THDF = Transformer Harmonic Derating Factor):
>1 or <1 for DISTORTED signals
=1 for SINUSOIDAL wave forms

Possibility of automatic transmission type "ONE WAY" (RS422) each second.
Possibility of display of just the single phase measures.
The 485 version is equipped with a RS485 serial output.

VIP ENERGY RPQS, VIP ENERGY RPQS 485
In addition to the measuring function, they are equipped with pulse output for industrial monitoring

2 SOLID STATE RELAY OUTPUTS with pulse frequency proportional to 2 out of the P (P+ or P- with COG4 option), Q (Q+ inductive or Q- capacitive), S (active, reactive, apparent) powers selection by keyboard.
In addition to the measuring function it is equipped with 2 solid state relay outputs, volt-free contacts (280VAC rms max. 100mA max.). They supply pulses with frequency proportional to the power measured.
A simple display menu and SELECT, SET push-buttons allow selecting 2 out of powers: active (P, P+ or P- with COG4 option selected), reactive (positive Q+ inductive, negative Q- capacitive), apparent (S) and different output frequencies according to requirements:
Min. 1 pulse= 1 MWh (Mvarh) (MVAh)
Max. 999 pulses= 1 Wh (varh) (VAh)
RPQ (P+ or P- with COG4 option, Q+ or Q-) selection: supplies pulses proportional to the active energy (P=W) and reactive (Q=var) for measurements of active energy (kWh) and reactive (kvarh).
RPS (P+ or P-) selection: supplies pulses proportional to the active energy (P=W) and apparent (S=VA) for measurements of active energy (kWh) and apparent (kVAh).
RSQ (Q+ or Q-) selection: supplies pulses proportional to the apparent energy (S=VA) and reactive (Q=var) for measurements of apparent energy (kVah) and reactive (kvarh).
The functioning of the relay can also be set with static procedure, with opening and closing checked through keyboard or RS485.
In the RPQS-485 version it is possible a remote control (by PC) of 2 loads.

VIP ENERGY ALM, VIP ENERGY ALM 485
In addition to the RPQS functions, they are are equipped with RELAY OUTPUT for alarm and load control

MINIMUM and MAXIMUM alarms on any 2 measurements chosen by the user from 27 of those displayed, with selection of the ON and OFF delay time (from 0 to 999 seconds) and of the MINIMUM and MAXIMUM threshold hysteresis (from 0 to 17.5% in steps of 2.5%) for each of the two relays which can be connected to the alarms.
The VIP ENERGY ALM-485 also has all the functions of the VIP ENERGY RPQS-485.
