The technical parameters of GE IS415UCVHH1A are optimized around two core goals: “stable power supply” and “industrial adaptability.” Key specifications include:
Voltage Conversion Performance
Input Voltage Range: 18V DC – 72V DC (covers voltage fluctuations from common industrial battery packs, such as 24V or 48V).
Output Voltage: 24V DC ±0.5% (voltage stability ≤0.1% under varying loads, preventing malfunctions in sensitive components due to voltage drift).
Output Current: 10A (rated) / 15A (short-term peak, up to 10 seconds) – sufficient to power 10–12 low-power modules simultaneously.
Maximum Output Power: 240W (24V DC × 10A) – matches the power demands of most components in the Mark VIe system.
Efficiency and Anti-Interference Capability
Conversion Efficiency: ≥92% (at 50%–100% load) – low energy loss minimizes self-heating of the module.
Output Ripple: ≤50mVpp (far below the industry average of 80mVpp), avoiding interference with sensor signal acquisition.
Electrical Isolation: Isolation voltage between input and output ≥2kV AC (for 1 minute) – prevents current crosstalk between circuits.
Reliability and Environmental Adaptability
Operating Temperature: -25°C to +70°C (tolerates extreme environments, such as high temperatures in thermal power plant turbine halls or low temperatures in outdoor settings).
Protection Functions:
Short-circuit protection (automatic recovery after fault resolution).
Overload protection (current limiting to 15A).
Over-temperature protection (shutdown at +85°C, restart when cooled to +70°C).
Reverse polarity protection (prevents damage from incorrect positive/negative wiring).
Mean Time Between Failures (MTBF): ≥5,000,000 hours (backed by GE’s industrial-grade component selection and structural design).
Mechanical Dimensions
Size: 120mm × 160mm × 40mm (compact design, compatible with standard DIN rail mounting in Mark VIe cabinets).
Weight: Approximately 300g – easy to install in space-constrained control cabinets.
