Hammond Power Solutions SP50MQMJ

Product identity

Product overview

SP50MQMJ is a Hammond Power Solutions HPS Spartan control-transformer reference. The Group C manufacturer table lists a 50 VA rating, 240 × 480 V primary and 120 × 240 V secondary connection options at 50/60 Hz. These paired voltage markings require the correct winding connections; they do not mean an automatically regulated output over a continuous input range. Use the exact catalog row and the offered unit nameplate when reviewing a panel requirement.

Before requesting this part

Send the full SP50MQMJ nameplate, quantity and required condition. Record the actual incoming voltage and frequency, required secondary voltage, continuous VA demand and load/inrush characteristics. Have the winding connections, primary/secondary protection, grounding and enclosure installation checked against the manufacturer instructions and panel design. Confirm mounting clearances and whether links, guards or fuse accessories are included in the offered unit; a brochure accessory list does not establish completeness. A different VA size or secondary code is a separate selection. Ask for actual-unit photos and an agreed transformer test, then specify destination and required date.
