CRT range – 24/48/110V – Three phase

Product catalog summary

Overview: The CRT range of battery chargers utilizes robust thyristor technology, making them compatible with various battery types including recombined sealed lead, open lead, calcium lead, classic lead, and nickel-cadmium batteries. These chargers are suitable for diverse applications such as marine, offshore, military, railway, and industrial sectors.

Certification: The chargers are Bureau Veritas certified with type approval number 04682/C0 BV.

Standard Range: The CRT range includes models with different output currents and case types, available for 24 Vdc, 48 Vdc, and 110 Vdc outputs. Each model is specified with item codes for both 230 Vac and 400 Vac power supplies, along with their respective weights.

Technical Specifications:

Input: 230 Vac or 400 Vac ± 10% three-phase, 50 or 60 Hz ± 5%.
Output: 24 Vdc, 48 Vdc, and 110 Vdc with specific floating voltages. Other voltages available upon request.
Technology: Thyristor controlled, rectified filtered technology with electronic current limitation and short-circuit protection.
Output Characteristics: Regulation of ± 1%, ripple < 5%, galvanic insulation, and I/U type charge.
Display and Control: Includes power on indicator, voltmeter, ammeter, and ON/OFF switch.
Protections: Input fuses, contactor, thermal relay, bipolar fuse, and protection against short-circuit and polarity reversal.

Mechanical and Climatic Specifications:

Case: Metal case with IP 23 rating, polyester finish in grey RAL7032, and salt atmosphere resistance.
Dimensions: Vary by case type, ranging from CFE20 to CFE250.
Operating Conditions: Temperature range from -10 to 50°C, storage from -20 to 70°C, and humidity from 0 to 95% without condensation.

Options and Standards: Additional outputs, voltage threshold control, charge fault PCB, insulation regulator, temperature probe, and dry contacts are available as options. The chargers comply with EC Marking standards and are designed to withstand on-board shocks and vibrations.
