Product Introduction
The Atos E-ME-AC-05F is an analog electronic driver engineered to control proportional valves without position transducers (or specific single-stage/multi-stage hydraulic control loops). Operating as part of Atos’s established E-ME-AC series, it processes incoming low-level reference commands (voltage or current) and supplies regulated, pulse-width modulated (PWM) current to the proportional solenoids of hydraulic valves.
The unit features onboard trimming potentiometers for adjusting parameters such as ramp times, bias, and gain, providing precise, repeatable open-loop control for industrial hydraulic power units, presses, and heavy machinery requiring high-speed response.

Compliance & Standards Alignment
- Designed and manufactured in compliance with relevant industrial electrical and CE electromagnetic compatibility (EMC) guidelines for industrial control apparatus.
- Utilizes conformal circuit protection to resist atmospheric humidity and standard industrial cabinet environments.
Technical Note: When adjusting the onboard potentiometers (ramps, gain, and bias) on the E-ME-AC-05F card, always use an insulated tuning tool and monitor feedback via test points to prevent hydraulic actuator over-acceleration or system instability.
Storage & Asset Preservation Guidelines
- Store the electronic card inside its original antistatic ESD shielding bag to protect sensitive analog semiconductors, operational amplifiers, and internal transistors from electrostatic damage.
- Maintain clean, dry warehouse storage environments where temperature is controlled and relative humidity remains below 60%.
- Avoid mechanical stress, bending, or dropping the board to prevent micro-fractures in the printed circuit substrate or edge connector contacts.
Physical Installation Prerequisites
- Ensure that all electrical power feeds, transformer lines, and hydraulic valve solenoid circuits are completely de-energized and locked out (LOTO) prior to card insertion or extraction.
- Mount the unit securely into its designated rack slot or sub-rack housing, ensuring clean, parallel alignment with the backplane or terminal block connector.
- Verify that wiring connections for command signals, power supplies, and solenoid outputs match the specific technical data sheet for your hardware revision tier (e.g., Series 20/21).
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this Atos electronic amplifier?
A: Industrial electronic control cards, amplifiers, and static converters for automation systems typically classify under HS code 8504.40 (Static converters) or 8538.90 (Parts for electrical control apparatus). Confirm final categorization with your licensed customs broker.
Q: Is the E-ME-AC-05F a direct drop-in replacement for older revision cards?
A: Minor series revisions (such as moving between early and later manufacturing iterations) can sometimes introduce layout updates. Always cross-reference the exact design code and suffix on your existing card faceplate before swapping.
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market conditions, inventory levels, and unit condition (Factory New, Surplus, or Refurbished); contact our technical sales desk for a formal, time-sensitive quotation.
