ARTES RC4 Specifications

Product catalog summary

Applications
The document describes a highly precise, portable measuring system designed for functional tests on various types of protection equipment. It supports three-phase tests on static and digital protection relays and can be operated via a PC with ARTES testing software or through a built-in control panel with a 5" touch screen, function keys, and a jog wheel.

Sources
All signals can be independently set for phase, amplitude, and frequency. The system includes internal feedback measurements to monitor output quantities, issuing warnings if discrepancies occur. It also features overload and short-circuit protection.

General Specifications

Frequency range: DC to 3 kHz (transient signals up to 4 kHz)
Frequency resolution: 0.001 Hz with an error of less than 0.01%
Phase angle: 0 to 360° with a resolution of 0.001° and an error of less than 0.05°

Voltage Outputs

4-phase (L-N): 0 to 300 V / 75 VA
3-phase (L-N): 0 to 300 V / 100 VA
1-phase (L-L): 0 to 600 V / 150 VA
Resolution: 10 mV with an error of less than 0.05%
Total Harmonic Distortion (THD): less than 0.05%

Current Outputs

3-phase: 0 to 25 A / 50 VA
1-phase: 0 to 60 A / 100 VA
Resolution: 1 mA with an error of less than 0.05%
THD: less than 0.05%

DC Output

Output range: 12 to 260 VDC
Output power: 50 W, max. 2 A
Accuracy: Error less than 5%
Protection: Overload and short-circuit protection

Binary Inputs
The binary inputs are organized into two groups, each with two measurement inputs, configurable for dry or wet contacts. They feature transient protection, polarity protection, and galvanic isolation via opto-couplers.

Binary Outputs

Relay: 2 relays with AC switching capacity of 0 to 250 VAC, 8 A, and DC switching capacity of 0 to 300 VDC, 50 W
Transistor: 2 transistors with a switching frequency of 1 kHz and capacity of 0 to 300 VDC, 50 mA

Complete System
The ARTES RC4 is housed in a robust hard shell case with protected interfaces and plugs. It includes a cable compartment for the cable set. Operation is possible via PC or stand-alone with a 5" touch screen, function keys, and a jog wheel.

Connections/Interfaces
Measurement connections use 4 mm safety sockets, and interfaces include USB and three Ethernet ports. Status LEDs indicate active outputs and binary input/output status.

Supply Voltage
Rated voltage is 100 to 265 VAC, 47 to 63 Hz, or 120 to 265 VDC with a wattage of 1200 W.

Construction
The housing is a hard shell case compliant with ATA 300, ASTM D-4169, and MIL-STD-810F standards, with IP67 protection when closed. Dimensions are 505 x 257 x 409 mm, and it weighs 16.9 kg.

Environment
Operating temperature is 0 to 50°C, storage temperature is -20 to 60°C, and relative humidity is 5 to 90%, non-condensing.

Generic Standards
The system complies with safety standard EN 61010-1, EMC standard EN 61326-1, EMC emissions standard EN 61000-6-4, and susceptibility standard EN 61000-6-2.

Catalog excerpts

Highly precise, portable measuring system for functional tests on various types of protection equipment. Four voltage and three current outputs allow three-phase tests on static and digital protection relays. The device can be operated and controlled either with a PC and the ARTES testing software or alternatively by means of the built-in control panel equipped with a high-resolution, resistive 5" touch screen, function keys and a jog wheel. All signals can be set separately and independently of one another as regards phase, amplitude and frequency. The output quantities of the current and voltage amplifiers are monitored by means of internal feedback measurements. If the output quantities do not agree with the setpoint values, a warning is issued to this effect. All outputs also have overload and short-circuit protection.
