LEN VIDEO ISOLATION TRANSFORMERS - Analogue

Blocking DC currents while remaining transparent to PAL and NTSC video signals, these transformers balance ground potential and eliminate hum interference. 'Severe' interference caused by 50 or 60Hz hum will be removed whereas normal 'humbucker' will only remove 'moderate' interference. At the same time they act as ground isolators, eliminating ground potential differences between equipment with 'minimal phase and gain distortion', preventing shocks to operators and damage to equipment.

Common specifications are as follows. Input and output impedance: 75 ohms. Ripple reduction: 120dB. Bandwidth: Better than 8Hz to 5.5MHz, - 0.5dB.

LVIT01

This is built in an ABS enclosure with mounting flanges, fitted with two female BNC connectors.

Breakdown voltage: Greater than 100V. Dimensions: 85 x 56 x 39 (l x w x h)mm excluding mounting flanges, 110mm length including flanges. Weight: 170g.

LVIT02

The LVIT02 offers a higher breakdown voltage than the standard LVIT01 as required for medical grade applications. It has an ABS enclosure with mounting flanges, fitted with two female BNC connectors.

Breakdown voltage: Greater than 4kV. Dimensions: 85 x 56 x 39 (l x w x h)mm excluding mounting flanges, 110mm length including flanges. Weight: 170g.

LVIT03

This heavy-duty model contains the same circuitry as the LVIT01, but is built in a metal 'fire-safe' housing, for such applications as public transport, military and marine environments. The outer casing is made of die-cast aluminium and the overall construction has increased NVH protection. Particular attention is given to minimising fumes under catastrophic fire conditions. The enclosure is diecast aluminium alloy, finished in black, textured, polyester-powder paint. All coating to circuit boards, transformer, and internal components is non-fuming.

Breakdown voltage: Greater than 100V. Dimensions: 117 x 94 x 34 (l x w x h)mm excluding mounting flanges, 148mm length including flanges. Weight: 360g. Temperature range: 0 to +50 degrees C, operating; -20 to +70 degrees C, storage.
