SCK-M-U-1500V — SOLARCHECK measurement module up to 1500 V DC
Phoenix Contact SCK-M-U-1500V 2903591 is a voltage transducer designed for monitoring photovoltaic installations and measuring DC voltage on the DC side of a PV system.
The module has one voltage input enabling measurement up to 1500 V DC in measurement category CAT III. The measured value is converted into an analog 2–10 V DC voltage signal, which can be used by a higher-level measurement system or photovoltaic installation monitoring system.
SCK-M-U-1500V belongs to the SOLARCHECK Phoenix Contact family and can work with other modules of the PV string monitoring system.
Measurement up to 1500 V DC in a compact module
1500 V DC
High DC voltage measurement enables the module to be used in modern photovoltaic installations.
2–10 V
A standard analog output signal makes it easy to transmit the voltage value to the measurement system.
SOLARCHECK
The module is part of the Phoenix Contact system designed for monitoring photovoltaic strings.
DC-side voltage monitoring in a photovoltaic installation
One measurement channel up to 1500 V DC
SCK-M-U-1500V has one DC voltage measurement input.
The maximum input range is 0–1500 V DC in measurement category CAT III. For applications compliant with UL requirements, the range is 0–1000 V DC.
The input resistance of the voltage path is 2 × 20 MΩ, which limits the effect of the measurement circuit on the monitored circuit.
Analog 2–10 V DC voltage output
The measured input voltage value is converted into a standard analog signal 2–10 V DC.
The signal can be used by a compatible SOLARCHECK system module or another measurement device with a suitable analog input.
The recommended cable type for the output signal is shielded twisted pair, and the minimum required output load is 10 kΩ.
Stable voltage measurement over a wide temperature range
The typical temperature coefficient of the module is less than 0.01%/K.
The maximum transmission error is ±1% after additional adjustment and applies to the measurement range from 100 to 1500 V DC.
The parameters allow the module to be used for continuous monitoring of PV installation voltage under changing environmental conditions.
Voltage control as part of string diagnostics
PV string voltage measurement is one of the basic parameters used when monitoring the operation of a photovoltaic installation.
Voltage data can support detection of irregularities related to PV module operation, cabling, connections and other elements of the DC circuit.
Combined with current measurement of individual strings, the SOLARCHECK system provides a more complete picture of photovoltaic installation operation.
Compatibility with string monitoring modules
SCK-M-U-1500V is part of the Phoenix Contact SOLARCHECK system designed for monitoring photovoltaic installations.
The module can be powered directly with 24 V DC or via a compatible SCK-M-I-8S-20A current measurement module.
The SOLARCHECK system also includes string current measurement modules and communication modules enabling the collected data to be transmitted to a downstream monitoring system.
Nominal 24 V DC power supply
The module operates at a nominal supply voltage of 24 V DC.
The permissible supply voltage range is from 21.6 to 30 V DC.
Typical self-consumption current is 8 mA, while the maximum is 65 mA.
Built-in overvoltage protection circuit
The module has an internal protection circuit including overvoltage protection and a 33 V suppressor diode.
The design is prepared for operation with voltages occurring on the DC side of photovoltaic installations and meets the requirements of applicable electrical safety standards.
The pollution degree specified by the manufacturer is 2.
Screw terminals for conductors up to 2.5 mm²
Electrical connections are made using screw terminals.
Solid and flexible conductors with a cross-section from 0.2 to 2.5 mm² are supported.
The recommended stripping length is 8 mm, while the terminal tightening torque is 0.5–0.6 Nm.
Operation from −20 to +70°C
Slim 22.5 mm module for DIN rail
SCK-M-U-1500V is designed for mounting on a standard 35 mm DIN rail.
The device width is only 22,5 mm, allowing the module to take up little space in a distribution board or measurement cabinet.
The overall module dimensions are 22.5 × 102 × 128.5 mm.
22,5 mm
The small width reduces the space required in the distribution board.
DIN 35
Standard mounting enables easy integration with installation equipment.
IP20
The enclosure is designed for installation inside a suitably protected cabinet or distribution board.
Design intended for industrial and PV installations
The module complies with the requirements of EN 61010-1 and EN 61010-2-30.
Electromagnetic immunity is specified according to EN 61000-6-2, while interference emission is specified according to EN 61000-6-4.
The product has CE marking and UL approvals for the US and Canadian markets.
