Main features

Thin profile design

Thin profile (21.5mm wide) for both 15A and 25A.

Capable of close mounting

A maximum 8 units can be closely mounted and the width is 172mm.

※When the units are mounted closely, the ambient temperature characteristics change.

Soft-start and soft-down functions are supplied as standard

Output slowly changes against a sudden change of input signal, suppressing the inrush current.

Available for manual control

Manual control is available by using an external variable resistor.

Main specification

  • Control method: Phase control (SSNP series), Zero-cross control (SSNZ series)
  • Maximum load capacity: 15A, 25A ac
  • Applicable load: Linear load (R: resistance)
  • Input signal: 4 to 20mA dc
  • Minimum load current: 100mA ac

Note: The conduction angle gets smaller in case of minute current load.

Before using this device in an actual application, it is recommended to conduct a test operation.

  • Leakage current at OFF: 9mA ac (RMS) or less (Load voltage: 200Vrms, 60Hz)
  • Response time: 1 cycle or less  (When soft-start is not used)

※Soft-start is disabled when the front POT is rotated fully counterclockwise.

  • Power supply frequency: 50/60Hz (automatically selected)
  • Standard functions: Soft-start/Soft-down function: approx.0.5 to 13 seconds (SSNP series), approx.0.5 to 40 seconds (SSNZ series)

External variable resistor (for manual control) ※Variable resistor is optional.

<General Specification>

  • Ambient temperature: -20 to +60°C
  • Power supply voltage (Rating): 100 to 240V ac
  • Weight: Approx. 260g
  • Safety standards: UL, cUL
