Description
The Model 440 is a medium energy, low voltage, capacitor discharge type magnetizer capable of
saturating Alnico and Barium Ferrite magnetic materials. The Model 440 is easily adapted to a wide
range of production and laboratory magnetizing requirements. A modern solid state electronic control
circuit, coupled with rugged, heavy duty discharge SCR and fixture, make this magnetizer a highly
reliable, low maintenance unit. The seven position voltage select control allows easy adjustment of the
capacitor voltage while an easy to read front panel meter monitors the capacitor voltage. Production
fixtures are easily manufactured for virtually all types of polar configurations.
The Model 440 Magnet Charger is designed for bench use or rack mounting in electronic enclosures.
The relatively low charging voltage (350 Volts maximum) and high capacity storage bank (7200 uF)
allows for the design of a wide range of simple and complex wire wound fixture designs. The charging
energy can be increased to 880 watt-seconds by connecting the Model 442 Booster unit.
An optional protective hood assembly (HB90455) incorporates an electrically interlocked
Plexiglass hood which provides a safe method
for testing "instant fixtures" which can greatly
assist in proving the design of engineering
prototype magnet assemblies. The protective
hood assembly is also used for magnetizing a
wide range of magnetic assemblies and other
applications where magnetizing windings may
be an integral part of a magnet assembly
structure.
The interlocked hood assembly prevents operators from coming into contact with the magnetizer
output and allows quick and easy hook-up of the magnetizing windings.
The Model 440 and HB-90455 utilize AN/Type connectors for rapid interchange of fixtures and the
hood assembly. A set of contacts, in the connector, is associated with the internal interlock circuitry of
the Model 440 and requires that external charging fixtures incorporate a safety interlock device to
provide operator protection.

Typical Peak Magnetizing Forces:
Peak H will depend upon the impedance of the charging fixture. A peak magnetizing force of
approximately 12,000 Oersteds can be achieved using an HD-31625 wire wound fixture.
* The times listed here are capacitor recharge times to 425 VDC. Lower voltages will produce faster
recharge times, however actual cycle times may vary depending on fixture cooling requirements and
input line voltage.
Power Requirements: 115 or 230 VAC 50/60Hz (Please specify at time of order)
115 VAC 7 Amps Average
230 VAC 3.5 Amps Average
Magnetizing Pulse Characteristics:
The Model 440 produces a sinusoidal half-wave pulse. Pulse shape and length will depend on the
impedance of the fixture used with this unit. A typical pulse with the Model 31625 wire wound fixture
will have a rise time of 8 ms to the peak and an overall pulse length of 35 ms is produced with the
Model 440. The rise time to the peak and overall pulse width will depend on the fixture impedance
and the capacitance of the magnetizer.
