Features

• Optimum Voltage Sensors for Voltage Detection and Alarm Applications
• Two types of voltage detection, single operation type (SDV-F) and double operation type (SDV-D), are available.
• Added series with single operation type timer function with on delay/off delay/power start lock timer (switched by switch) operation function. (SDV-FH □ T)
• Overcurrent and undercurrent can be detected by the combination with the flow divider type SDV-SH.
• For AC voltage and DC voltage. (Both SDV-F and -D are switched by the switch.) • Can switch between DC polarity and non-polarity for DC micro-input exclusive products (SDV-FL).
• The return value adjustment range can be adjusted more widely. (2~30% Model SDV-F)
• Equipped with a light emitting diode for operation display convenient for operation inspection. (Shape SDV-F, -D) • Acquired safety standard UL and CSA. (SDV-F)
