Description

Nunome Electric NESB330CUL09705-03 330VA Transformer 200/220V to 100/110V 1-Phase

The Nunome Electric NESB330CUL09705-03 is a single-phase, open-frame step-down power transformer rated at 330 VA. It converts a 200V or 220V primary input to a 100V or 110V secondary output at up to 3 amps, making it well suited for powering Japanese-spec equipment from standard industrial AC lines. Manufactured by Nunome Electric Co., Ltd. of Nagoya, Japan, and UL listed (cULus), this unit dates from 2000 and carries a Class 130 insulation rating.

Applications

Step-down transformers of this type are commonly used in industrial and manufacturing environments to power Japanese-market equipment — such as CNC controllers, machine tool accessories, and automation components — from 200V or 220V facility power. The 200/220V primary range covers standard three-phase-derived single-phase industrial voltages widely found in factories throughout North America and Europe, while the 100/110V secondary matches the voltage standard used by equipment designed for the Japanese domestic market. At 330 VA, this transformer is sized for small to medium control circuits, instrumentation, and auxiliary loads rather than large motors or main drive power. Open-frame transformers like this one are typically panel-mounted or chassis-integrated inside a larger enclosure or machine cabinet. The cULus listing confirms compliance with North American and Canadian safety standards, making it suitable for use in UL-required installations.

Condition: Used
This Nunome Electric NESB330CUL09705-03 330VA step-down transformer has been inspected and appears to be in good used condition. The laminated core and coil windings look intact, and the terminal blocks show no signs of burning or damage. The chassis shows normal surface oxidation and light scuffing consistent with age and prior industrial use — cosmetic only. The rating plate is fully legible.
