SECTION 1 SECTION 1 PT SERIES CONTROL TRANSFORMERS SECTION 9 PT Series Control Transformer - Applications The HPS “PT” series of machine tool transformers, now ‘CE Marked’, are specifically designed for high inrush applications requiring reliable output voltage stability. Designed to meet industrial applications where elec- tromagnetic devices such as relays, solenoids, etc. are used, the HPS “PT” series transformers maximize inrush capability and output voltage regulation when electromagnetic devices are initially energized. STANDARDS Hammond Industrial and Machine Tool Control and Instrument Transformers meet or exceeds the standards established by UL, CSA, IRC, ANSI, NEMA. Standard File # VA Size UL (ANSI/UL 506) E50394 All PT CSA (C22-2 No. 66) LR3902 All PT IEC 989 All Molded PT’s NEMA (ST-1) All PT At HPS, we rate the VA capacity of our transformers at the output ..... where it counts. Other transformer manufacturers rate their capacity on the input side of the transformer, which can result in a 5% to 20% lower actual VA at the output. 33 Data subject to change without notice. © Hammond Power Solutions Inc.
