LOW VOLTAGE GENERAL PURPOSE TRANSFORMERS

Our transformers have provided distributed power in the most

demanding environments for the past 90 years. ey feature

full isolation with shielding and NEMA-3R, NEMA-4/12 and

NEMA-4X stainless steel optional enclosures.

Features

• UL Listed/NEMA Type 3R ventilated outdoor enclosures

when used with optional weather shields (order separately)

• UL Class 220°C insulation system, 150°C temperature rise

under full load

• Terminal board connections and spacious wiring compartment

• Panel enclosure design reduces labor time. Wiring diagram on

inside front cover.

• High eciency for low cost operation

• Compliant to NEMA TP-1 Standards

• Single and three phase availability

• Fast delivery

• Ten year limited warranty

Applications

• Oce/commercial buildings

• Shopping centers

• Municipal/institutional buildings

• Hospitals

K-Factor Transformers are designed to reduce the heating

eects of harmonic currents. e K-Factor rating is an index

of the transformer’s ability to withstand harmonic content

while operating within the temperature limits of its insulating

system. SolaHD K-Factor transformers have UL ratings of

K-4, K-13, and K-20.

Features

• Conductors to carry harmonics of a K-rated load without

exceeding insulation temperature ratings

• UL 1561 listed up to K-20 rated protection

• Rated temperature rise of 150°C, 220°C insulation

• Shielded for quality power

• Basic design takes “stray losses” into account and functions

within safe operating temperatures

• Core and coil design engineered to manage the zero sequence

ux caused by triple harmonics

• Provides 100% rated current without overheating the

windings or saturating the core

Applications

• Telecommunications equipment

• Uninterruptible power supplies (UPS)

• Solid state motor drives
