The HS/HSN Series offers
greater power capacity (100
and 250 watts) in the same
design format as Ohmite’s 89
Series.
HS/HSN Series maintains
the same construction, materi-
als, and manufacturing tech-
niques as the 89 Series. As
a made-to-order product, it is
recommended for higher vol-
ume applications.
