DTS-200K-D0

Product Description

The DTS-200K-D0 is a premium station service transformer designed synchronously for utility-scale energy solutions from Huawei. The device steps down high voltage from the system to standard low-voltage power to feed all monitoring, control, and outdoor cooling systems, helping the plant seamlessly maintain its operational self-sufficiency.

Key features

• Premium Dry-Type Transformer Design: Utilizes dry-type transformer technology with Aluminum (Al) windings and Class H insulation, ensuring high operational safety, explosion-proof capabilities, and zero oil leakage concerns.

• Superior Smart Heat Dissipation: Integrates an air-forced (AF) cooling method with an architecture that requires no cross-flow ventilation, maximizing equipment availability and extending component lifespan.

• Intelligent Protection & Management: Equipped with integrated temperature-based monitoring and protection sensors that proactively trigger alarms or protective trips upon detecting hazardous overheating states.

• Flexible Output Distribution: Supports output cable connections to a system of 5 low-voltage Molded Case Circuit Breakers (MCCBs), with each MCCB capable of concurrently connecting to 2 load outputs.

• Harsh Environment Endurance: All circuit boards and the transformer core are strictly protected inside an IP55-rated enclosure, allowing flawless outdoor operation across a wide temperature range of -30°C to 55°C.

Why choose the DTS-200K-D0?

• Ultra-low Operational Losses: Optimized design minimizes energy waste with a no-load loss of ≤ 500 W and a load loss of ≤ 3,044 W.

• Comprehensive Surge Protection: Equipped with a built-in Type II Low Voltage Surge Protective Device (LV SPD) to protect internal consumption loads from sudden voltage surges.

• Compliance with Stringent International Standards: The product fully complies with prestigious international industrial standards, including IEC 60076 and IEC 61439.

• Clean Wiring Architecture: Bottom entry and exit design for all power and signal cables keeps the overall station neat and prevents water ingress.

• Flexible Installation: Provides a robust floor-mounted installation solution, ideal for deployment alongside STS turnkey stations or battery containers.

• Synchronized Huawei Ecosystem: Transmits status data via dry contacts, allowing easy integration into the Smart PVMS cloud-based management platform.
