The LDV-250 250W Waterproof Power Supply is an industrial-grade AC/DC converter optimized for environments where water, dust, and mechanical stress are common challenges. Its IP67 protection rating ensures complete protection against dust ingress and temporary submersion in water (up to 1 meter for 30 minutes), making it ideal for outdoor and harsh-industry applications.
Input voltage range: 180～264 VAC (47～63Hz) or 255～373 VDC, accommodating global industrial power grids.
Efficiency levels: 82% (12V model), 84% (24V model), and 85% (36V model) – reducing energy waste and operational costs.
Physical dimensions: 23012555mm (LWH) and weight of 2.42Kg, enabling easy integration into space-constrained setups.
Ripple & noise control: 150mVp-p (12V model) and 200mVp-p (24V/36V models), ensuring clean power for sensitive electronics.
This power supply is not only built for durability but also for compliance with international safety and EMC standards, making it a versatile choice for global industrial projects.
The LDV-250’s design prioritizes performance, protection, and adaptability – addressing the unique needs of industrial and outdoor applications.
Energy efficiency: With efficiency ratings ranging from 82% to 85%, the LDV-250 minimizes heat generation and energy loss, extending its lifespan and reducing long-term operational costs.
Stable power output: Voltage tolerance of ±1% and load stability of ±0.5% ensure consistent power delivery, critical for sensitive equipment like marine navigation systems or oil/gas sensors.
Low inrush current: Cold-start current of 40A/230VAC prevents power grid spikes during startup, protecting both the power supply and connected devices.
The LDV-250 includes multi-layer protection to safeguard against common industrial hazards:
Short circuit protection: Activates in fault conditions to prevent component damage.
Overload protection: Triggers at 105%~135% of rated load (hiccup mode, auto-recovers after fault removal).
Over voltage protection: Thresholds set at 15~17V (12V model), 30~32V (24V model), and 42~44V (36V model) – preventing voltage surges from harming devices.
High-temperature protection: Cuts off output at ≥85℃ and auto-recovers once temperatures return to safe levels, ideal for hot oil/gas fields or direct sunlight exposure.
Its IP67 certification is a standout feature, providing:
Complete dust tightness (no dust ingress, even in dry, dusty oil/gas environments).
Protection against temporary water submersion, making it suitable for marine applications where splashes or accidental submersion may occur.
Operating temperature range: -10℃~+60℃ (20%~90% RH), allowing use in cold marine climates or hot industrial sites.
Storage temperature range: -20℃~+85℃ (10%~95% RH), ensuring durability during transportation or offline storage.
Vibration resistance: Withstands 10-500Hz, 2G vibration (10min/cycle, 60min total per axis), suitable for mobile marine equipment or oil/gas field machinery.
Safety standards: Meets EN61347-1 and EN61347-2-13, ensuring adherence to European industrial safety regulations.
EMC standards: Complies with EN55015, EN61547, and EN61000-3.4 CLASS B, minimizing electromagnetic interference (EMI) with nearby electronics.
The LDV-250’s combination of waterproofing, protection, and efficiency makes it suitable for diverse industrial and outdoor use cases.
Marine environments demand power supplies that resist saltwater corrosion, humidity, and vibration – all addressed by the LDV-250. It powers:
Navigation equipment (GPS, radar systems).
On-board LED lighting and communication devices.
Sensors for water depth, temperature, or cargo monitoring.
In oil/gas fields, where dust, temperature extremes, and electrical hazards are prevalent, the LDV-250 supports:
Remote sensors (pressure, flow rate, or gas detection).
Outdoor control panels for drilling or pipeline operations.
Emergency lighting systems in harsh field conditions.
The LDV-250’s stable output and IP67 rating make it ideal for:
Streetlights, parking lot lighting, or landscape LED installations.
Industrial outdoor lighting (e.g., factory yards, construction sites).
Its low ripple & noise (150-200mVp-p) ensures flicker-free LED performance.
Moving signs, billboards, or traffic signs require reliable power in all weather. The LDV-250 powers:
LED-based digital billboards in rain, snow, or dust.
Traffic control signs (e.g., speed limit or construction warnings).
For equipment exposed to harsh conditions, the LDV-250 supports:
Portable industrial tools (e.g., outdoor power drills, sensors).
Weather stations or environmental monitoring devices.
