Clamping” Tran-

Model 18D/E SCR controls provide

infinitely variable control of sin-

gle-phase (18D) and three-phase

(18E) a.c. voltages to resistive heat-

ing elements. These units are solid

state replacements for variable

transformers, saturable core reac-

tors, electromechanical contactors,

and mercury relays. Power semi-

conductors replace contacts and

brushes to switch electric power

without moving parts, and, when op-

erated within stated ratings for cur-

rent, voltage, and temperature,

have no known MTBF or life

expectency rating.

18D/E SCR controls incorporate ex-

clusive design features to protect

the power semiconductor compo-

nents against damage:

1> Unique “V

unmatched protection for power

semiconductors against transient

voltage spikes common on indus-

trial power mains.

2> “2 millisecond” fuses protect

semiconductors against short-cir-

cuit faults. Payne Engineering SCR

controls are the only power controls

in the industry equipped with factory

tested and approved fuses coordi-

nated with power semiconductors.

3> Proprietary heatsinks are engi-

neered in-house coordinating finite

element analysis (FEA) with on-site

lab tests. Payne Engineering SCR

controls operate at 50

ambient temperatures with no derat-

ing.

Standard configuration of all 18D/E

controls is for manual control via a

Standard options allow for open- or

closed-loop automatic control in re-

sponse to an analog control signal

from a temperature controller, PLC

I/O module, or other external

source. Other options allow controls

to be configured for the specific re-

quirements of each application.

Power Circuit: inverse-parallel

semiconductors selected for V

Clamping transient protection, with

parallel R-C circuit for dv/dt protec-

tion. Current-clamping 2-millisec-

ond power fuses in series with

power semiconductors provide

short-circuit protection.

Control Circuit:all solid state cir-

cuitry supplies synchronized gate

pulses to each thyristor via isolating

pulse transformer.

Mains Frequency: 50, 60 Hz

stan-dard. Other frequencies avail-

able as special order (consult fac-

tory).

Output Voltage:0 to nominal input

voltage, infinitely variable.

Overall Efficiency: 98.5 to 99.5%.

Power Loss: approximately 1-2

watts/ampere/switched pole.

Voltage Drop Across Power Circuit

at 100% Output:1-2 volts maximum

per switched pole.

Proof Voltage:(isolation between

power circuit, control circuit and

ground) greater than 2 kV.

Control Input:manual control via

75K Ohm, 2 watt potentiometer with

integral On/Off switch and indicating

dial plate standard.

Control Power:5 watts maximum.

Derived from 12 VA isolation control

transformer (except for 120 VAC

18D units in 10, 20, 30 amp sizes).

Fuse Protection:2 millisecond I

fuses are factory tested and coordi-

nated with all power semiconduc-

tors, considering:

Transient Voltage Protection: volt-

age breakover (V

R-C filters for dv/dt protection.
