[Yuken] — SK1115 Power Amplifier for High-Performance Power-Saving Valve (ELFBG-03)
Family ID: YK-SK1115
Yuken DC-input power amplifier for the high-performance proportional power-saving valve ELFBG-03. Provides LVDT spool-position feedback, a slope (ramp) function and an alarm output for stable, high-accuracy flow control. The compensation code (1 or 2) is matched to the valve flow rating (1 = ELFBG-03-125, 2 = ELFBG-03-170). Max output current 2.5 A, command input 0 to +10 V, input impedance ≥10 kΩ, sensor-monitor output -0.5 V/1 mm stroke, alarm output max DC30V/10 mA. Supply DC24V (20–30 V incl. ripple), mass 0.3 kg. No power switch (operates as soon as powered — fit an external switch).
