ANG variable autotransformers are made in seven basic series or frame size V1 – V3 – V5 – V10 – V20 – V40 – V70.
Electrical specifications are given in the detailed tabulations for the various models.
Optional features can be provided.
Single and three phase:
Single phase – suffix “V”
Three phase – suffix “T”
All basic variable transformers are available in uncovered form.
These units are designed with the suffix: NA (ex V5 NA Single phase uncovered, T5 NA Three phase uncovered).
All single units and ganged assemblies are available in styled enclosure.
Suffix: NC (ex V 5 NC single phase covered).
V1 – V3 – V5 – V10 – V20 series can be supplied in portable cases with carrying handles, input lead, switch, output fuse.
A digital voltmeter LED (suffix PV) can be provided. The portable models are also available with volt-meter and ammeter (suffix PVA).
In the models covered and portable the output can be taken through:
socket type “schuko” (up to 10 A) suffix SCH
CEE socket 16-32-64 A suffix CES16, CES32, CES64 insulated terminals suffix ILT.
All open and covered voltage regulators are available with reversing motor drive for remote control and automatic applications.
Suffix: M (ex V 5 NA/M is a motor-drive single phase open construction-uncovered).
All voltage regulators are available assemblies of two, three, four, five, six units operating on one common shaft for parallel or series. The number following the suffix NA or NC indicated the number of ganged regulators (add SR for series connection).
Example: V 70 NA/6-M is a single phase uncovered motor-drive regulator with six units in parallel. V 70 NA/2SR-M two units series connection.
Non standard voltage or non standard current, limit switches, special shaft and special motors can be supplied to customer’s special requirements.
