ULTRA ISOLATION TRANSFORMER
Did you know that most AC power lines are superimposed with dangerous spikes, surges, transients, sags, RFI noise and harmonics?
This is due to Inductive and SMPS loads, electronic ballasts, PWM switching systems, or even improper earthing. Such electrical noise often damages costly Hi-Tech machinery, unduly interrupt factory operations and increase down time resulting in increased expenses. The lack of adequate protection in such environments results in the steady rise of failure rate in such equipments. Isolated power supply has therefore become a necessity in order to prevent such breakdown time and costs.
Ultimate Protection against Electrical Noises
As an Ultra Isolation Transformer, Unity’s Tranquil is the most powerful solution to help eliminate all types of noise, particularly Common Mode Noise, Spikes, Surges and Transient Noise, which act as silent killers inside factories and commercial parks alike.
The Tranquil series offers transformers with various levels of noise attenuating capabilities, including the most commonly used 100 and 120 dB, and other custom requirements can also be met.
Designed for Energy Efficiency & Reliable Performance
Tranquil transformers are built to meet the stringent requirements of the most sophisticated equipment being used today, resulting in a clean and noise-free power supply. Each Tranquil is intelligently designed using advanced technologies and proven engineering principles to provide reliable performance and energy efficiency year after year. Furthermore, by completely isolating primary and secondary sides as well as the neutral to ground bond on the secondary side, Tranquil creates a separately derived power source to combat current loops.
Key features
Total Protection
Shields electronic equipments that produce different types of electrical noise, typically CNC Machines, Drives, Hardening machines and Telecommunication equipment
Energy Efficient
Reduces operating costs due to high efficiency design and high quality of magnetics
Noise Elimination
Prevents damage due to circulating noise interference within electronic equipments
Causes of Electrical Noise
Electrical utilities such as Capacitors, MCCB’s, ACB’s and Inductive loads such as large Motors, Compressors, Overhead Cranes, Elevators,
Presses cause switching noise
Welding systems can pollute earthing systems, add notches and high frequency noises in the wave form, generating anomalies in power quality
Inverters, Converters, SMPS cause electrical noise due to switching of Thyristors, Transistors and Relays
Effects of Electrical Noise
Occurring over a wide band of frequency ranging from 1KHz to 100 MHz or more, in magnitudes as high as 4000-6000 Volts on 3 Phase supply systems
High frequency noise can interfere with digital electronic equipment and cause untraceable data errors, change of programme, memory loss and erratic
machine behaviour
High voltage spikes can cause the failure of Thyristors, Transistors, Microprocessors, etc.
