Compact
structure
Compact, lightweight and high panel
installation density

|
Options
The options of
heater disconnection alarm function and current limit
function are available. |
|
|
Phase-angle
firing/zero-cross firing
The phase-angle firing
system and the zero-cross firing system are
selectable. The running by the phase-angle firing
system at the initial stage and by the zero-cross
firing system at the normal stage is possible. |
|
|
Zero-cross firing
system
With the delta-sigma modulation, which
controls every 1 cycle, the fine control like the
phase-angle firing system is possible.
|
|
|
Setting unit
(option)
Display of various parameters,
voltage/current/ power and change of the feedback
system are possible. |
|
|
Various protections
functions built-in
The thyristor element is
protected by melting of the rapid fuse for
short-circuit of load, and by gate-off for
over-current. For models with a cooling fan built-in,
alarm is activated and output is stopped for abnormal
heat-sink temperature.

|
|
Self-diagnosis function
built-in
The self-diagnosis function is built in
for abnormal operation, abnormal thyristor element and
abnormal power supply. |
