Lightning-resistant transformer LT series by Tsuruta Electric, low voltage transformer.
The LT series transformer, designed to minimize damage from lightning surges, is essential for remote locations and unmanned facilities.
The JISC6436・JEC2200 standard-compliant lightning-resistant transformer LT series ensures a surge attenuation rate (transition rate -60dB) with the standalone lightning transformer, capable of reducing the ratio to as much as 1000:1. The attenuation rate is calculated as 20 log Vs/Vp (dB) [Vp primary voltage, Vs secondary voltage]. ■Specifications■ *Primary voltage: E and H types are 200V, F type is 100V (MAX 400V series) *Secondary voltage: E and F types are 100V, H type is 200V (MAX 400V series) *Rated capacity: 200VA to 10kVA *Insulation class: A, B, F *Frequency: 50/60Hz ■Electrical Performance■ *Voltage fluctuation rate: 5% or less for 200VA to 2kVA, 3% or less for 3kVA and above *Insulation resistance: 100MΩ or more at DC100V megger *Withstand voltage: AC10kV for 1 minute (between primary and secondary windings and installation) *Impulse withstand voltage: 30kV (1.2x50μs) (between primary and secondary windings and installation) *Surge transition rate: Common mode -40 to +60dB or less *Noise: 60dB or less (at a distance of 1m from the outer surface)
