Why Choose a Sine‑Wave UPS for Home Use

• Clean & Stable Output: Pure sine wave UPS provides a smooth AC signal, which is safe for sensitive electronics (PCs, smart appliances, medical devices, etc.).

• Better Compatibility: Many modern power supplies (especially for PCs) use Active PFC, and they work reliably with pure sine wave outputs.

• Longer Device Lifespan: Using clean power helps reduce stress on electronics, which can increase their lifespan.

• Flexible Backup: Depending on the UPS capacity, you can power different combinations of devices during load-shedding or blackouts.

• Reliable Charging & Switching: Good sine-wave UPS units from Orient Computers offer intelligent charging and fast automatic switch-over to battery power.

Key Features & Benefits of Sine‑Wave UPS from Orient Computers

1. Pure Sine Wave Output
   Ensures the power waveform is smooth — just like main grid power — making it safe for all kinds of electronic equipment.

2. Flexible Battery Compatibility
   Many models support both lead-acid and lithium batteries, giving you flexibility based on your budget and usage.  

3. Intelligent Charging
   Adjustable AC charging current (0–20A) helps optimize battery performance and longevity.  

4. Multiple Operating Modes

   • AC First: Uses AC (mains) when available, then switches to battery.

   • DC First: Prioritizes battery usage when possible.

   • Energy Saving: Balances between AC and battery to maximize efficiency.
      

5. UPS (Automatic Switch)
   These IPS units can instantly switch to battery power during outages, protecting your devices from sudden shutdowns.  

6. Smart LCD Display
   Real-time monitoring of battery voltage, load, charging current, and system status.  

7. Wide Input Voltage Range
   Some models support very wide AC input (for example, 65–140V and 135–280V), making them resilient to voltage fluctuations.  

8. Robust Protections
   Includes overload, short-circuit, and over-temperature protection to safeguard both the UPS and connected devices.  

How to Choose the Right Sine‑Wave Home UPS

Here are some practical tips when selecting a sine-wave UPS for your home:

1. Estimate Your Load

   • List the devices you want to run during an outage: PC, monitor, router, lights, etc.

   • Sum up their wattages or VA requirements.

2. Choose Appropriate VA Rating

   • 1000VA: For basic electronics or a single PC.

   • 1500VA or more: For multiple devices or higher load.

   • 2000VA+ / Hybrid IPS: For heavy loads / long backup.

3. Battery Voltage & Type

   • 12V for lower-power UPS models.

   • 48V or higher for larger IPS/hybrid systems.

   • Decide between lead-acid and lithium based on cost and how often you use battery power.

4. Operating Mode Selection

   • Use Energy Saving if you want to reduce electricity cost.

   • Use AC First if you rely mostly on grid but want backup in outages.

   • Use DC First if your battery is large and you want to prioritize it.

5. Check Input Voltage Tolerance
   If your area has very unstable or fluctuating voltage, choose a UPS that supports a wide input voltage range.

6. Consider Backup Time
   The capacity of your battery (AH rating) will largely determine how long you can run your devices.

7. Service & Warranty
   Purchase from Orient Computers to ensure you get genuine products + warranty and after-sales service.

Frequently Asked Questions  

Q1: What’s the difference between pure sine-wave and square‑wave UPS?
A: Pure sine-wave produces a smooth AC waveform, which is safer and more stable for sensitive electronics. Square-wave or modified sine-wave is cheaper but may not be ideal for power supplies with Active PFC or very sensitive devices.

Q2: How long will a 1000VA sine-wave UPS last?
A: It depends on the battery capacity (AH) and the load. A small 12V battery may give a few minutes; a larger battery gives longer runtime.

Q3: Can I connect tubular batteries to these sine-wave IPS units?
A: Yes, many of the models (like 1500VA and 2000VA) are designed to work with tubular plate batteries, which give longer backup life.  

Q4: Will my PC be safe with this UPS?
A: Yes — pure sine-wave UPS is ideal for PCs, especially if your power supply uses Active PFC.

Q5: Does the UPS switch instantly during a power cut?
A: Yes, UPS / IPS units are designed to switch to battery mode quickly to prevent shutdown of connected devices.

Q6: Is lithium battery supported?
A: Some hybrid IPS models support lithium batteries, but make sure to check the model’s spec.
