Application Scenarios
At a copper smelter in Chile operating at 3.800 meters altitude, ambient temperatures regularly exceed 45°C, and grid voltage sags occur daily due to nearby arc furnaces. The plant’s AC 800M-based furnace control system previously suffered unexplained controller resets traced to power instability. After replacing legacy power supplies with ABB 3BHE019719R0101 modules configured in 2+1 redundant mode, zero power-related failures occurred over 36 months—even during a 220 ms brownout event. The module’s wide input range and active current sharing prevented any disruption to molten metal temperature control, safeguarding $ 12M/day in production value.
Technical Principles and Innovative Values
Innovation Point 1: True Fanless Redundancy for Harsh Environments
Unlike competing units that require forced air cooling, the 3BHE019719R0101 uses advanced thermal design to dissipate 240 W without fans—eliminating a major failure point in dusty, corrosive, or explosive atmospheres (ATEX/IECEx zones via proper enclosure).
Innovation Point 2: Seamless N+1 Parallel Operation with Active Load Balancing
Up to three units can be paralleled with < 5% current imbalance, ensuring no single module is overstressed. If one fails, others instantly compensate—maintaining full system power without controller reboot.
Innovation Point 3: Dual-Mode Input (AC/DC) for Grid Resilience
Accepts both AC mains and DC battery/bank inputs—ideal for hybrid power systems in remote mines or offshore platforms where backup DC sources are standard.
Innovation Point 4: Integrated Diagnostics for Predictive Maintenance
The built-in FAIL relay integrates directly into System 800xA alarm management, enabling early warnings for capacitor aging or thermal drift—long before total failure occurs.
Application Cases and Industry Value
In a Norwegian subsea oil well control pod, two 3BHE019719R0101 modules powered redundant AC 800M controllers managing Christmas tree valves at 3.000 m depth. The fanless design prevented salt-induced corrosion, while the wide DC input range allowed direct connection to the platform’s 220 V DC emergency bus. During a surface power loss, the system transitioned flawlessly to battery backup—keeping critical safety functions online for 72 hours.
Similarly, at a U.S. nuclear fuel fabrication facility, the 3BHE019719R0101’s SIL 3 compliance and electromagnetic resilience (tested per IEC 61000-4-5 surge immunity) made it the only approved power solution for reactor coolant monitoring racks—where even microsecond power glitches could trigger regulatory shutdowns.

Installation, Maintenance, and Full-Cycle Support
The 3BHE019719R0101 installs into compatible ABB chassis (e.g., TB870) using a slide-in latch mechanism. Wiring requires:
Input: L/N/PE (AC) or +/- (DC)
Output: +24 V, 0 V, and optional alarm relay contacts
Redundancy setup involves connecting all +24 V and 0 V terminals in parallel with diode-or’ing (built into baseplate). No configuration software is needed—operation is fully hardware-managed.
We validate every unit through:
96-hour burn-in at 70°C and 10 A load
Surge testing (±2 kV line-to-line, ±4 kV line-to-ground)
Redundancy switchover verification under 100% load
Output ripple measurement (< 50 mVpp)
