Description
Designed to save valuable PC board space, the 20 Watt NT
Dual series is ideal for use in battery operated industrial,
medical control and remote data collection systems. Each unit
is completely filtered to reduce noise, has an exceptionally
low input/output capacitance and provides efficiencies to
85%.
Complete overload protection with independent pulse-by-
pulse current limiting and an overtemperature shutdown
circuit ensure zero-failure rate operation. Their copper cases
are five-sided, shielded and water washable.
