SmartPro 230V 500VA/300W Line-Interactive Rack/Tower UPS with AVR & Network Card Option

SmartPro 230V 500VA 300W Line-Interactive UPS, 1U Rack/Tower, Network Card Options, USB, DB9 Serial, Half Load 17Min, Full Load 5 Min, PDU Integration Capability – C14 input; 7 C13 outlets; 2 C13 to C14 cables

Product Description

The SmartPro 230V 500VA 300W Line‑Interactive UPS (model SMX500RT1U) is a rack‑mountable or tower uninterruptible power supply designed for small network closets, servers, telecom equipment, and other sensitive electronics that need reliable battery backup and power conditioning. It fits in 1U of rack space or can be placed upright as a tower.

This UPS uses line‑interactive technology to provide surge protection, battery backup during power outages, and automatic voltage regulation (AVR) to correct brownouts and overvoltage without draining the battery. It helps prevent data loss and hardware damage from power interruptions and fluctuations.

Power & Performance

• Capacity: 500 VA / 300 W — supports small servers, network switches, routers, storage devices and similar loads.
• Runtime: Approximately 17 min at half load and 5 min at full load, giving you time to save work or shut down equipment safely.
• 230 V output: Nominal voltage for many international and enterprise environments.

Inputs & Outputs

• C14 inlet input: Connects to your mains via a detachable power cord.
• 7 C13 outlets: Provides multiple power connections for your equipment; often includes a mix of UPS‑supported and surge‑only outlets.
• Includes 2 C13‑to‑C14 cables: These jumper cables let you power devices directly from the UPS.

 Monitoring & Control

• USB & DB9 (serial) ports: For local computer connection to monitor UPS status and enable automatic shutdown via software.
• Network card slot (optional): Allows remote monitoring/control with an SNMP or web card installed (sold separately).
• Front panel LEDs & alarms: Indicate status, power mode, overload and battery conditions at a glance.

 Protection Features

• Automatic Voltage Regulation (AVR): Helps maintain steady output voltage during brownouts/overvoltages without battery use.
• Surge and noise filtering: Reduces electromagnetic and RFI interference to protect connected gear.
• Emergency Power Off (EPO) interface: For rapid shutdown in emergency situations (cabling included).

 Form Factor & Installation

• 1U rackmountable or tower configuration: Includes hardware for mounting in a standard 19″ rack or using as a standalone unit.
• Compact design: Takes minimal space while offering robust protection.

 Ideal Uses

Perfect for protecting small business servers, network closets, VoIP systems, security systems, and other critical electronics where clean, reliable power and uptime are important

Why Choose

Here’s why you might choose the SmartPro 230V 500VA 300W Line‑Interactive UPS for your setup — in clear, practical terms:

1. Reliable Protection for Critical Gear

This UPS guards your equipment against:

• Power outages — keeps devices running long enough to save work or shut down safely
• Voltage fluctuations — automatic voltage regulation (AVR) corrects brownouts and surges without draining the battery
• Electrical noise — filters spikes and interference that can harm sensitive electronics

👉 Ideal for network hardware, small servers, VoIP systems, and business‑critical electronics.

2. Flexible Installation

• 1U rackmount or tower form factor — fits comfortably in a rack or sits on a shelf
• C14 input and C13 outputs — standard commercial power connectors
• Includes two C13‑to‑C14 power cables — ready to hook up equipment

Whether you’re building a server rack or protecting mission‑critical gear in an office closet, the installation is straightforward.

3. Smart Monitoring Options

You get multiple ways to monitor and manage power:

• USB & serial (DB9) ports — connect to a computer for automated shutdown and status reporting
• Optional network card slot (SNMP/Web) — remote insight and control over your UPS
• Front panel LEDs & alarms — at‑a‑glance status alerts

This makes it easier to integrate into managed environments.

4. Useful Runtime for Small Loads

With a 500 VA / 300 W capacity:

• ~17 min at half load
• ~5 min at full load

This isn’t a huge battery, but it’s enough to:

• Finish tasks
• Save files
• Power down safely
  without abrupt shutdowns.

It beats losing data or risking hardware problems during outages.

 5. Line‑Interactive for Better Voltage Handling

Line‑Interactive UPS systems like this one:
✔ Correct voltage dips and surges without switching to battery
✔ Reduce wear on the battery
✔ Provide more stable output than simple standby UPS models

This strikes a good balance of performance and cost for small IT and network equipment.

 6. Particularly Suited For:

• Small business networks
• Server closets
• Security systems (CCTV, NVRs)
• Office routers, switches, firewalls
• VoIP / communication systems
• Remote sites without heavy power infrastructure

When Not to Choose It

This model is not ideal if you need:
❌ Very long backup times
❌ Support for loads much greater than 300 W
❌ A double‑conversion (online) UPS for extremely sensitive or mission‑critical equipment

In those cases, you’d choose a larger UPS or an online topology.
