Products Description
High-Efficiency, Stable Power Core for Modern Agricultural Machinery: K18-UP400S22 V3 Switching Power Supply
In modern agricultural operations-from automated seeders and drone-based spraying systems to smart irrigation controllers-equipment reliability directly impacts productivity. Designed for the harsh operating conditions of agricultural machinery (voltage fluctuations, dust, vibration, and wide temperature variations), we introduce the K18-UP400S22 V3 series switching power supply. Engineered for efficiency and compactness, this power supply delivers clean, stable 407W output specifically tailored for 22V DC-powered agricultural equipment.
Key Advantages
1. Universal Input, Adaptable to Complex Grid Conditions
Agricultural sites often rely on end-of-line grids or temporary power sources with severe voltage fluctuations. This power supply features an ultra-wide AC input range of 90V–264V and built-in active PFC (Power Factor Correction), achieving a power factor of up to 0.98. It ensures stable operation even in remote farms with unstable voltage and enables efficient energy use, reducing grid pollution-ideal for use with diesel generators.
2. Ultra-High Efficiency, Green and Energy-Saving
With a peak efficiency of 93% at 230V AC input, low power loss translates to reduced heat generation, extended equipment lifespan, and significant electricity savings-critical for long-duration operations like grain drying or nighttime irrigation. Its compact size (127×82×38mm) allows easy integration into space-constrained control enclosures.
3. Precise and Stable 22V Output
Optimized for agricultural loads such as motors, solenoids, and sensors, it delivers 22V DC output with a rated current of 18.5A and peak power of 407W. Output accuracy reaches ±1%, with ripple and noise controlled under 500mVp-p, ensuring stable operation of voltage-sensitive control circuits (e.g., GPS navigation modules, PLC controllers). An adjustable output range (20.5V–24.5V) offers added flexibility for diverse equipment needs.
4. Comprehensive Protection for Harsh Environments
Agricultural machinery faces risks from dust, transient overloads, and short circuits. This power supply integrates multiple protections:
Overload/Short Circuit Protection: Latch-off mode (requires power cycle), preventing repeated arcing and potential fire hazards under severe faults.
Output Overvoltage Protection: Auto-recovery "hiccup" mode when voltage exceeds 120%, safeguarding downstream devices.
Input Undervoltage Protection: Automatically shuts down when input drops below 75VAC, preventing excessive current and circuit damage.
Fan Power Interface: Onboard CN3 connector provides 12V/0.2A output for external cooling fans (Note: A fan with minimum 15CFM airflow is required when power exceeds 350W).
5. Wide Temperature Range, Robust and Durable
Operates reliably from -20°C to 60°C, ensuring stable startup and performance in cold northern winters or hot, humid southern greenhouses. It has passed 10–500Hz vibration testing, meeting the demands of mobile agricultural machinery. With an MTBF exceeding 250,000 hours, it delivers outstanding reliability.

FAQ
Q: The power supply has a wide input voltage range (88-264VAC). Can it really be used directly in any country around the world without adjustment?
A: Yes. The 400W series power supply is designed with a full-voltage input that works in all countries. When the single-phase AC power grid voltage in your area is between 88V and 264V (covering standard voltages like 100V, 115V, 220V, 230V, 240V, and so on) and the frequency is between 47Hz and 63Hz, the power supply can automatically adapt and work normally. You don't need any manual switching or adjustment.
