What are the main protection features of the AS-PS02?

It includes Overvoltage Protection (OVP) to prevent damage from voltage spikes. Overcurrent Protection (OCP) and Short-Circuit Protection (SCP) safeguard against excessive current draws. These features protect both the power supply and connected devices.

Over-Temperature Protection (OTP) is also integrated to prevent overheating. If the internal temperature exceeds safe limits, the unit will shut down. This feature is vital for maintaining operational integrity and longevity.

These combined protections ensure a reliable and safe power source for critical industrial equipment. They minimize the risk of downtime and costly repairs due to electrical faults. This makes the AS-PS02 a dependable choice.

Can the Delta AS-PS02 be used in extreme temperatures?

The unit operates reliably within a wide temperature range of -20°C to +70°C. This broad operating window makes it suitable for diverse industrial environments, including cold storage or hot production areas. Always ensure adequate ventilation.

Exceeding the specified temperature limits can reduce efficiency and lifespan. If operating at the upper end of the range, ensure proper airflow. Consider heat dissipation in enclosed control cabinets.

For applications outside this range, alternative solutions or environmental controls may be necessary. Always refer to the product's datasheet for precise operating parameters and limitations. Consult Delta for specialized environmental requirements.

What is the typical efficiency rating of the AS-PS02?

The AS-PS02 boasts an efficiency rating typically above 88%. High efficiency means less energy is wasted as heat, leading to lower operating costs. This also contributes to a smaller environmental footprint for your operations.

This high efficiency is achieved through advanced power conversion technology. It allows for a more compact design by minimizing the need for large heat sinks. This is beneficial for space-constrained industrial panels.

Improved efficiency also translates to greater reliability, as less heat is generated internally. This is crucial for applications requiring continuous operation in demanding conditions. It supports longer component lifespan.

What kind of input voltage does the AS-PS02 accept?

It accepts a wide AC input voltage range, typically from 100V to 240V. This global compatibility simplifies deployment across different regions with varying power grids. It accommodates common single-phase AC power sources.

This broad input tolerance reduces the need for external voltage converters. It simplifies inventory management and installation in multinational projects. It offers flexibility for diverse power environments.

How does Overload Protection (OCP) work on the AS-PS02?

OCP limits the output current to a safe level when the load exceeds the specified maximum. If the current draw is too high, the power supply will reduce its output or shut down to prevent damage. This protects the unit and the load.

The OCP is designed to allow for temporary current surges, such as motor startup. However, sustained overloads will trigger the protection mechanism. This ensures the power supply remains operational under normal conditions while guarding against faults.

If OCP is activated, troubleshooting the connected load is necessary to identify the cause of the excessive current. Once the overload condition is resolved, the unit typically resets automatically or requires a power cycle. Check the manual for reset procedures.

Is the Delta AS-PS02 suitable for use in hazardous locations?

The standard AS-PS02 is designed for general industrial environments. It is not inherently certified for hazardous locations (e.g., explosive atmospheres). Use in such areas requires specialized, certified equipment.

For hazardous area applications, consult Delta's product catalog for intrinsically safe or explosion-proof power supply options. Using the wrong type of equipment can create significant safety risks and regulatory non-compliance. Always verify certifications.

Ensure that any power supply used in potentially hazardous zones meets the specific ATEX, IECEx, or other regional certifications required. Compliance is critical for personnel safety and operational integrity. Specialized units are engineered with enhanced safety features.

What is the physical size and mounting method for the AS-PS02?

The AS-PS02 features a compact form factor, with dimensions typically around 125mm x 125mm x 130mm (WxHxD). This compact design is ideal for installation in space-constrained industrial enclosures. It minimizes the footprint within control panels.

It is designed for easy and secure mounting onto a standard 35mm DIN rail. This is a common mounting standard in industrial control cabinets, simplifying integration with other components. The DIN rail system ensures quick installation and removal.
