1 Variable Transformers Product Selector Guide ISE, Inc Royalton Rd. - Cleveland, OH USA - Tel: (440) Fax: (440)
2 The STACO Variable Transformer Product Quick Selector is a guide to all standard single-phase and three-phase variable transformers in the Staco product line including portable, ganged and motorized models. Units are listed by voltage rating and by increasing values of current and KVA. With known values of voltage, current and frequency, the STACO Variable Transformer Selector can be used to locate the particular transformer that best fits your requirements. If a motor driven model is ordered, be sure to prefix the part number with the desired travel time, typically 5, 15, 30 or seconds. For non-standard operating conditions, refer to the Product Design and Engineering Section of this catalog. Ratings and configurations not included in the Variable Transformer Selector may be obtained by consulting our STACO representative or by contacting the factory B PN221B B, 511 M501-B 5,15,30, PN501B B M1010B 5,15,30, PN1010B B M1210B 5,15,30, 3PN1210B M1510B 5,15,30, PN1510B PN2210B M2510 5,15,30, M ,15,30, M5011 5,15,30, M11 5,15,30, M ,15,30, P M5011-2P 5,15,30, P M11-2P 5,15,30, P M5011-3P 5,15,30, P M11-3P 5,15,30, P M5011-4P 15,30, P M11-4P 15,30, P M5011-5P 15,30, P M11-5P 15,30, P M5011-6P 15,30, P M5011-7P 30, P M11-6P 15,30, P M5011-8P 30, P M11-7P 30, 32

See pages 30, 31, 32, 33 & 34. Constant Current Load the normal rated output amperes may be drawn at any position of the brush except in voltage doubler connections. Constant Impedance Load an increased current may be drawn at the maximum voltage output (Limited to line voltage) provided the current reduces proportionally as output voltage is lowered. Voltage Doubler (half rates voltage input). Normal rated amperes may be drawn from 0 to 125% of the input voltage. At outputs above this, the load current must be reduced according to the derating guide. Figure B, page 6.
