Description
Core Product Summary (Brand / Model / Key Attributes)
The ATOS E-ME-AC-05F is an analog electronic driver in Eurocard format designed for Atos proportional valves without pressure or position transducers. The 05F version is specifically intended for double-solenoid proportional valves.
It regulates the current supplied to the valve solenoids according to an external electronic reference signal, thereby controlling spool position, flow or pressure. The driver provides a maximum solenoid current of 3.3 A (PWM square-wave) and accepts a nominal ±5 V reference signal. Bias and scale adjustments are performed via potentiometers, and a symmetrical ramp generator is included as standard. Power supply is +24 VDC (rectified and filtered 21–33 V) with a maximum consumption of 50 W. The unit is supplied in DIN 41494 Eurocard format with a DIN 41612 connector.

Detailed Product Overview
The ATOS E-ME-AC-05F belongs to the E-ME-AC family of analog drivers used to control the current delivered to the solenoids of Atos proportional valves that do not incorporate a pressure or position transducer. By modulating the solenoid current in response to an external reference signal, the driver determines the hydraulic spool position and therefore the resulting flow or pressure.
The 05F designation indicates suitability for double-solenoid valves. A PWM square-wave current amplifier supplies up to 3.3 A to each solenoid (reduced to 2.5 A for explosion-proof versions). Factory pre-setting of the nominal ±5 V reference simplifies commissioning, while front-panel potentiometers allow independent adjustment of bias (dead-band compensation) and scale. A symmetrical rising/falling ramp generator limits acceleration and deceleration of the reference signal, improving system stability and reducing hydraulic shock.
The driver is built in the standard Eurocard format (DIN 41494) and plugs into a DIN 41612 connector, making it suitable for modular rack or panel installations. Enabling is performed by a 5–24 VDC signal. Optional versions with asymmetrical ramps (/RR) or internal reference potentiometers (-4, /RR-4, /4R-4) extend functionality for more complex control schemes.
Engineering Selection Highlights
- Select the 05F version when controlling double-solenoid proportional valves without onboard transducers.
- Use the standard symmetrical ramp for most applications; choose /RR options if independent rise and fall times are required.
- Power supply must be a clean +24 VDC source (21–33 V after rectification and filtering).
- Solenoid current is limited to 3.3 A continuous (PWM); verify valve coil resistance compatibility.
- Reference signal is factory-set to ±5 V; scale can be adjusted between ±2.5 V and ±10 V.
- Eurocard format requires a matching DIN 41612 female connector and suitable rack or panel mounting.
- Maximum ramp time of 5 s covers typical industrial hydraulic response requirements.

Verification & Troubleshooting Notes
- Confirm the valve is a double-solenoid proportional type without transducer before applying the E-ME-AC-05F.
- Verify power-supply voltage remains within 21–33 V under load.
- Check that the reference signal polarity and amplitude match the factory ±5 V setting or the adjusted scale.
- Use the front-panel potentiometers only for bias and scale; incorrect adjustment can cause offset or saturation.
- Ensure solenoid cables are correctly sized and shielded when length exceeds 20 m.
- Observe the enable LED to confirm the enable signal is present.
