LTC1000-SC/SP27: Closed-Loop Hall Effect High-Current Measurement Sensor

LTC1000-SC/SP27 Core Advantage: Closed-Loop Hall Technology – The Ideal Choice for Precision High-Current Measurement

The LTC1000-SC/SP27 is a high-accuracy current sensor based on the closed-loop Hall effect principle. Its core design uses a magnetic balance compensation structure to precisely measure DC, AC, and pulse currents, with a rated primary current of 1000 A and a wide measurement range. Compared with open-loop Hall sensors, closed-loop technology offers significant advantages in zero drift, linearity, response time, and temperature stability. It is therefore the preferred choice for demanding high-power, high-current applications such as converters, frequency inverters, and power supplies.

How it works: A closed-loop Hall sensor generates a compensating magnetic field through a secondary coil to cancel the field produced by the primary current, keeping the magnetic core at zero flux. This eliminates non-linearity errors inherent in the core, delivering measurement precision and stability that are difficult to achieve with conventional open-loop sensors.

LTC1000-SC/SP27 Precise & Reliable – Proven in Harsh Industrial Environments

High accuracy & excellent linearity
The LTC1000-SC/SP27 guarantees outstanding measurement accuracy (overall accuracy: ±0.8%) and superior linearity, capturing current variation with true fidelity.

Wide operating temperature range
Supports -40℃ to +70℃, making it ideal for outdoor applications in regions with large seasonal temperature differences, such as China.

Low temperature drift & fast response
Even in complex electromagnetic environments, the sensor provides excellent immunity to interference and a fast response time, delivering real-time, stable measurement of grid or control loop conditions.

Advanced electrical isolation
The high-insulation plastic housing provides a test isolation voltage of up to 13.4 kV (RMS) between primary and secondary circuits, ensuring personnel safety and signal integrity in high-voltage applications.

Flexible mechanical mounting
Equipped with four M5 bolts and four Faston (6.3 x 0.8 mm) connectors, the sensor offers two mounting options to suit different field wiring and fixing requirements, greatly simplifying on-site installation and retrofitting.

Upgrade from Traditional Technologies – Ready for Future Smart Applications

The LTC1000-SC/SP27 is an ideal upgrade or replacement for older measurement technologies such as reed switches or float-type level/current sensors. Its applications include:

Power & energy sector – DC side current monitoring in PV inverters, current sampling in BMS for energy storage systems, main circuit current measurement in frequency inverters.

Industrial automation & heavy manufacturing – instantaneous current capture in servo drives, high-current control in welding machines and cranes.

New energy & transportation – main/auxiliary converters in rail transit, real-time current monitoring in electric vehicle charging modules.

Beyond these, in building automation and smart water management, the LTC1000-SC/SP27 is equipped with a powerful RS485/RS232 serial communication interface and standard isolated analog output. It can be easily integrated as a core component into building BAS systems, smart water plant DCS control systems, networked energy monitoring platforms, or dual-sensor differential measurement (e.g., upstream vs. downstream trash rack level difference at hydropower stations).

Why Choose the LTC1000-SC/SP27?

When you need a reliable current/level measurement solution for critical equipment or next-generation smart products, the LTC1000-SC/SP27 delivers clear advantages: more accurate energy and status monitoring, rock-solid system protection, and seamless integration into automation and IoT networks.
