JMB Series Low Voltage Landscape Lighting Transformer – NEMA 3R
Product Overview
The JMB Series Low Voltage Landscape Lighting Transformer is specially designed for indoor and outdoor low-voltage lighting applications. Featuring a NEMA 3R weather-resistant enclosure, it supports 380V/220V input voltage and customizable 36V/24V/12V output voltages. With power capacities ranging from 500VA to 15KVA, it is widely used in construction sites, tunnels, roads, factories, dormitories, landscape lighting, and machinery lighting systems.
This transformer provides safe, stable, and reliable low-voltage power supply for various lighting applications.
Key Features & Advantages
1. Safe and Durable Structural Design
Flame-Retardant Metal Enclosure
Constructed with thick cold-rolled steel plates, the enclosure offers excellent fire resistance, impact resistance, and corrosion protection. Multi-side ventilation louvers improve heat dissipation and moisture resistance, ensuring long service life in demanding outdoor environments.
Clearly Marked Wiring Terminals
Input and output terminals are clearly labeled (such as 380V, 220V, 12V, etc.), making installation simple and convenient. The transformer supports quick external wire connection for plug-and-use operation.
Portable Handle Design
Integrated side handles make transportation, installation, and maintenance easier, especially suitable for temporary lighting applications on construction sites and tunnels.
2. Reliable Materials & Manufacturing
High-Quality Silicon Steel Core
Built with tightly laminated premium silicon steel sheets to reduce no-load losses and maintain stable voltage transmission. The transformer delivers clean power output with minimal waveform distortion.
High-Temperature Resistant Wiring
Internal wiring uses heat-resistant conductors combined with durable terminal blocks, ensuring stable long-term performance and reduced failure risks under continuous operation.
