Caltest Instruments GmbH

Kappelrodeck, Germany, July 2026 - Caltest Instruments now offers the latest performance enhancements for the Pacific Power Source AGX, RGS and RLS Series, providing even more powerful solutions for demanding AC/DC power test applications.

The updated systems now deliver up to 24 kVA/kW per 4U chassis and can be scaled up to 1.296 MVA/MW, enabling significantly higher power density without increasing rack space requirements.

„ The increased power density gives our customers greater flexibility when designing new test systems while maintaining the proven platform architecture. Existing installations can therefore be expanded quickly and easily. “

François Epp, Managing Director, Caltest Instruments GmbH

More Power for Growing Test Requirements

As power requirements continue to increase across AI data centers and UPS systems, renewable energy, defense, robotics and automation, battery storage, aerospace, automotive and e-mobility applications, the demand for scalable and energy-efficient test solutions continues to grow.

The latest generation offers:

• Up to 24 kVA/kW per 4U

• Up to 216 kVA/kW per rack

• Parallel systems up to 432 kVA/kW

• Three-phase configurations up to 1.296 MVA/MW

• Up to 48 Arms per phase from 45 Hz to 200 Hz

• Optimized load capabilities for high-frequency applications

Three Platforms for Different Test Applications

As the exclusive Pacific Power Source distributor for Germany, Austria and Switzerland (DACH), Caltest Instruments offers the complete product family:

AGX Series – Regenerative four-quadrant AC/DC power source supporting AC, DC, AC+DC and DC+AC operating modes for versatile testing of electrical and power electronic systems.

RGS Series – Regenerative grid simulator designed for grid compliance testing, anti-islanding verification and applications according to IEEE 1547 and UL 1741.

RLS Series – Regenerative AC/DC load simulator for realistic testing of power supplies, inverters, battery systems and other power electronic devices.

Lower Energy Consumption – Higher Efficiency

Utilizing modern silicon carbide (SiC) technology, the systems regenerate more than 90% of the absorbed energy back into the utility grid. This significantly reduces operating costs, cooling requirements and overall energy consumption, particularly during continuous high-power testing.

The integrated SmartSource Suite further simplifies test automation and remote operation through any standard web browser.

Complete Support from Consultation to System Integration

As the exclusive Pacific Power Source distributor for the DACH region, Caltest Instruments supports customers far beyond product selection. From designing individual test systems to implementing scalable high-power installations, customers benefit from application consulting, system integration, commissioning and technical support from a single source.
