Chances are that you can exactly match the requirements of your application from the extensive POWERSTAT® Variable Transformer line. To meet the needs of applications requiring higher ratings and/or remote operation, motor driven and multi-deck units in ratings to 365 KVA also are available from Allied Electronics. Motor driven units have the identical electrical ratings of their corresponding manually operated models. Models in the manually operated 10C-12C series are available up to three decks only. Models in the 21-22, 116C-216C, 117C-217C, 126-226, 136B-236B and 146-246 series are also available up to three decks only but have a motor drive option, which permits standard speeds of 5, 15, 30, or 60 seconds for full range travel. All 1156D-1256D and 1296D units are available with motor drives. Standard speeds for full range travel are 5, 15, 30 or 60 seconds for single units and two- and three-deck assemblies; 15, 30, or 60 seconds for four-, five- and six-deck assemblies; and 60 seconds for 14- through 27-deck units. Motorized unit options include either synchronous, or digital motor drives. The digital motor drive can be controlled in adjustable speed or digital control modes. Units up to nine-deck also are available for manual operation if desired.
