The lower price is due to simplified electronics and the lack of additional features, not lower standards. ESSENTIAL power supplies are manufactured in the same facilities as QUINT POWER and TRIO POWER and undergo identical quality tests. It is still a fully-fledged Phoenix Contact product – branded, certified and adapted to work in demanding industrial environments.

Key features of ESSENTIAL POWER power supplies

• 35 mm DIN rail mounting – quick and convenient installation,
• stable 24 VDC output with overload and short-circuit protection,
• wide range of AC and DC input voltages – resistance to power fluctuations,
• efficiency exceeding 90% – lower energy losses and lower temperature in the cabinet,
• operation in a wide temperature range (-25…+70°C),
• compliance with EMC and safety standards (CE, UL, IEC).

Thanks to these parameters, ESSENTIAL is a reliable power source for PLCs, sensors, relays and small HMI panels.

Where is ESSENTIAL suitable?

The ESSENTIAL series is the ideal choice in situations where:

• the installation does not require advanced diagnostics or redundancy,
• quick installation and low failure rate are important,
• optimal cost while maintaining quality is important,
• a stable 24 VDC voltage is required for sensors, controllers, and I/O modules.

Phoenix Contact ESSENTIAL power supplies are used in small OEM machines, building automation, HVAC systems, auxiliary switchgear, and conveyor lines.

ESSENTIAL vs. TRIO and QUINT

The choice of the appropriate power supply series depends on the application requirements:

• ESSENTIAL POWER - for simple systems and budget projects.
• TRIO POWER - for standard machines and applications requiring greater resilience.
• QUINT POWER - for critical systems with full diagnostics and redundancy.

This approach allows you to optimise the costs of the entire power supply system - we only use more sophisticated power supplies where they are really needed.

Compatibility and expansion

ESSENTIAL power supplies can be easily integrated with Phoenix Contact buffer modules, DC UPS systems, and surge protection devices. This makes it possible to create a complete, modular power supply system based on products from a single manufacturer, which can be expanded with additional functions as needed.

ELTRON support

As an authorised Phoenix Contact distributor, ELTRON supports customers in selecting the right ESSENTIAL power supply model, provides technical documentation and ensures fast product availability. Our engineers help you select the power, protection and any accessories to ensure that the proposed power supply system is tailored to your application.

ESSENTIAL POWER is a line of power supplies that proves that budget does not mean inferior. It is a branded, certified and reliable solution for projects where simplicity and reliability are important. Stable output voltage, high efficiency and easy installation make the ESSENTIAL series of power supplies a sensible choice for most standard automation applications.
