Product Overview
Full Wave
Input
NOTE: For brake response times with
and without AC rectifiers see page 97.
Output
A rectifier in which both positive and negative half-cycles
of the incoming (AC) signal are rectified to produce a
unidirectional (DC) current through the load. The DC
output voltage of a full wave rectifier is V
Maximum operating voltage is +10% ofnominal,frequency 50/60 Hz, maximum ambient temperature range of -40°C to 65°C
Half Wave
DC=
.90V
AC
Input
Output
A rectifier in which only alternate half-cycles of the
incoming (AC) signal are rectified to produce a
unidirectional (DC) current through the load. The DC
output voltage of a half wave rectifier is V
DC=
.45V
AC.
Maximum operating voltage is +10% of nominal, frequency 50/60 Hz, maximum ambient temperature range of -40°C to 65°C
Combination Full and Half Wave
Provides option of utilizing either full or half wave rectification
Maximum operating voltage is +10% of nominal, frequency 50/60 Hz.
Maximum ambient temperature range is -40°C to 65°C
TOR-AC Full and Half Wave
Provides coil turn off nearly as fast as DC side switching. Includes line filter for AC drive applications or whenever electrical
filtering is required to protect the rectifier from high-frequency electrical line pulses. Must be switched on/off by a switch in an
AC lead of the TOR-AC. Maximum operating voltage +10% of nominal, frequency 50/60 Hz.
Maximum ambient temperature range is -40°C to 65°C
QuickSet
A rectifier that provides a quick brake response time even when the rectifier is permanently wired
across the windings of an AC motor. The QuickSet Rectifier detects the decaying, motor generated
voltage that occurs when power is removed from the motor circuit, and interrupts brake coil current
in response. QuickSet Rectifiers can be specified full wave or half wave.
Operating voltage is ±10% of nominal, frequency 50/60 Hz.
Maximum ambient temperature range is -40°C to 65°C
QuickSet/QuickRelease
A rectifier that provides a timed, full wave rectified “over-excitation” brake release
function, followed by continuous, half wave rectified brake released “holding” function,
when used in conjunction with an appropriate brake coil voltage rating.
USED AS WATTSAVER: Provides a timed, full wave rectified brake release function, followed by continuous, half wave
rectified brake released “wattsaver” function, when used in conjunction with an appropriate brake coil voltage rating. The
Wattsaver serves to reduce the electrical power consumption and dissipation of the brake in the released state. Operating
voltage is ±10% of nominal,
frequency 50/60 Hz. Maximum

number - see information by part number

Bi-Phase Rectifiers
A rectifier that is typically used in single phase, reversing, permanent
split capacitor (PSC) motor applications. A single phase, reversing,
PSC motor typically has two windings of equivalent resistance. The
winding which serves as the main winding is connected directly
across the power line, the winding which serves as the auxiliary
winding is connected in series with a run capacitor across the power
line. The direction of rotation is reversed by interchanging the
function of the two windings. The Bi-Phase Rectifier provides the
same voltage to the brake coil regardless of the direction of rotation
of the motor. The Bi-Phase Rectifier has five leads and comes in
standard response and QuickSet versions. Bi-Phase Rectifiers are
application specific. Please contact factory for more information.
