Series
Two-in-one multifunctional digital controllers for
Strobe/PWM
LED controllers compatible with lighting modes from strobe overdrive to continuous lighting.
Allows adjustment of not only light emitting time but also voltage for dimming control in strobe
overdrive mode—invaluable for maintaining a constant light emitting time for setting cameras.
This proprietary function is an industry first for DIN-rail-mountable compact controllers.
• Mode selectable between strobe overdrive, strobe, and PWM
Adaptable to various lighting modes ranging from strobe overdrive to
continuous lighting
• Ethernet communication
Ethernet/parallel (8-bit) port provided for external interfacing
• Strobe dimming control
Allows adjustment of not only light emitting time but also voltage for
dimming control in strobe overdrive mode. This proprietary function is an
industry first for DIN-rail-mountable compact controllers
• Compact, lightweight body design
• Panel indication for easy operation
User-friendly panel indication allows easy operation
Selectable 3 Lighting Modes
Ethernet LAN/Parallel Digital Networking
Selectable three LED lighting modes, Strobe Overdrive, Strobe and
PWM are available for user’s precise lighting adjustment.
The Ethernet port and conventional parallel port interfaces are
equipped as standard. Setting up a LAN can be made by using the
existing IT assets, e.g. cabling, without additional cost.
