Saelig Intros Dynamic Current Loggers for Hybrid Autos
Dynamic current logger.
Pittsford, NY — Saelig Company, Inc. has introduced KLARI-MOD SC 1000V, new dynamic measurement modules specially designed for current and voltage measurements in automotive hybrid or electrical powertrain systems. An unusual feature is the 1000V safety isolation between measurement circuitry and data output. The new product enables fast measurements of up to 8,000 samples per second, previously unavailable in a logging module with these specifications.

For safe and proper automotive hybrid vehicle integration, OEMs and suppliers must be able to reliably and repeatably measure energy flow of system and individual currents and voltages over the full measurement range, without temperature drift. The new modules are designed to assist in the collection of dynamic voltage and current measurements, offering 16-bit resolution, extremely wide dynamic range, and isolation of 1000V between measurement circuitry and data output, gathering data at up to 8,000 samples per second, said to be the fastest technology available for this market.

Modules can be easily adapted to meet changing measurement requirements by using different shunts or voltage probes for low, medium and high current applications, with data output available via CANbus or RS-232 serial interface. Measurement connection points can be customer-specific, or simply by fuse replacement.

An automotive hybrid measurement system must work transparently without affecting vehicle performance, and independently of sensors installed on the production vehicle. It must also meet emerging automotive legislative and OEM safety requirements, such as SAE J1711 Emission and Fuel Economy Testing, J1772 Conductive Charging, J2464 Battery Pack and Capacitor Pack Safety and J2894 Charging Power Quality. These standards are only just beginning to be defined within the global automotive hybrid market.

Overall safety of both sensor and measurement modules is absolutely essential to such hybrid vehicle testing applications, ensuring that both possess sufficiently high insulation for safe measurements on the high-voltage side (per EN 60664).

Manufactured in Europe by Stefan Klaric GmbH & Co. AG and widely used by European automobile manufacturers, KLARI-MOD SC 1000V is now available in North America from Saelig.
