AIMS Power 5000 Watt Negative 48 Volt Rack Mount Pure Sine Inverter

The AIMS Power 5000 Watt Negative 48 Volt Rack Mount Pure Sine Inverter Delivers 5000 Watts of 120V AC Backup With a 50A Automatic Transfer Switch

The AIMS Power 5000 Watt Negative 48 Volt Rack Mount Pure Sine Inverter converts -48V DC battery power into 120V AC pure sine wave power in a 2U rack mount chassis. It delivers 5000 watts continuous and 10,000 watts surge, with a built-in 50A automatic transfer switch, two 15A outlets, an AC terminal block for hardwiring and RS485 communication.

AIMS designed it for telecom infrastructure, server racks and data center equipment powered by a negative 48 VDC battery system. When utility power is available, the transfer switch passes it through to connected equipment. If utility power fails, the inverter switches to battery power in under 20 milliseconds, keeping networking equipment, servers and monitoring systems running.

AIMS Power 5000 Watt Negative 48 Volt Rack Mount Pure Sine Inverter Features

Pure Sine Output From Two Parallel Sections

A digital signal processor (DSP) generates 120V AC pure sine wave power from two 2.5 kW sections working in parallel. AIMS lists total harmonic distortion of 1.2% at 1000W, a maximum efficiency of 93% and a continuous efficiency of 92%. Output runs at 60 Hz, and a front panel switch selects 60 Hz or 50 Hz.

50A Automatic Transfer Switch

The internal relay transfer switch is rated 50A. In bypass mode, utility (city) power feeds your equipment. When utility power fails, the inverter takes over from the -48V DC battery in under 20 milliseconds and returns to utility power automatically once it's restored. AIMS lists switching times of 6 ms on and 16 to 19 ms off (±2.5 ms).

Two Outlets Plus a Hardwire Terminal Block

Two 15A 3-prong outlets handle plug-in loads. A 3-pole AC terminal block (neutral, earth, hot) lets you connect equipment directly, which AIMS describes as the way to get the full output power of the inverter. Separate 50A high speed breaker switches protect the output and the city power input.

RS485 Monitoring and Front Panel Display

The RS485 port lets a PC read DC input voltage, AC output voltage, AC current and frequency through an RS485 to USB converter. Several inverters can share one converter, each with its own RS485 ID from 1 to 99. On the front panel, an LED display with UP and DOWN buttons shows output voltage, output current, frequency and input voltage.

Protection for Battery and Equipment

The inverter shuts down at low battery voltage (-40.2V, returning at -42.5V) and at high input voltage (-61.0V, returning at -59.0V). It also protects against output overload, output short circuit and over temperature, with a red LED and alarm to flag faults. AIMS lists a 60V, 80A input fuse on the DC side.

2U Chassis With Automatic Cooling

The 2U chassis measures 16.5 x 21 x 3.75 inches and weighs 31.5 lbs. Two front fans run automatically based on load and temperature and turn on at 104°F (40°C). If the inverter gets too hot, it shuts down and returns to operation at 136.4°F (58°C).

10,000 Watt Surge for Startup Loads

The surge rating is twice the continuous rating. AIMS says the inverter can hold that 200% surge for 500 milliseconds, which helps start devices with quick startup surges.

Real-World Applications

Telecom sites. Run 120V AC telecom equipment from a -48V DC battery system, with automatic transfer when utility power drops.

Server racks and data centers. Back up servers, computers and network hardware from a 2U unit in a standard equipment rack.

Equipment rooms. Keep routers, hubs and monitoring systems online during outages and watch several inverters from one PC.

Audio-video equipment. AIMS lists audio-video equipment among the uses for this pure sine inverter.

Practical Comparison

Pure Sine Rack Mount Inverter Versus a Modified Sine Inverter

A modified sine inverter produces a stepped waveform that some sensitive electronics don't handle well. This model's DSP-generated pure sine output, with 1.2% THD at 1000W, is designed for sensitive loads such as telecom equipment and computers.

Built-In Transfer Versus an Inverter Without One

An inverter without a transfer switch runs its loads from the battery all the time, so using utility power takes a separate device. This model passes utility power through and switches to battery in under 20 milliseconds on its own.

Outlets Versus the AC Terminal Block

The two 15A outlets suit equipment with standard plugs. The terminal block suits a permanent, direct connection, and AIMS recommends having a professional electrician make it.

Buyer Guidance

Match Your Battery System and Load

This inverter is for negative 48 VDC (-48V) battery systems with an operating range of 41 to 60 VDC negative. AIMS says to match the battery voltage to the inverter input voltage before connecting and not to reverse polarity. Keep continuous loads at or below 5000 watts. AIMS recommends keeping motor loads such as refrigerators and hand tools within 60% of maximum output, and running audio and video devices at 75% to 80% of listed capacity.

Wiring and Placement

AIMS's minimum DC cable size for this 5000 watt model is 6 AWG, with a cable under 12 feet long. A longer run needs a larger gauge. The earth connection uses 8 AWG. Keep the AC output cord to 50 feet or less. Allow plenty of ventilation, keep the inverter out of direct sunlight and away from moisture and flammable materials, and don't install it in a sealed area.

This May Be A Good Fit If

• You run a negative 48 VDC battery system
• You need up to 5000 watts of 120V AC
• You want a 50A automatic transfer switch
• You plan to monitor inverters over RS485
• You have 2U of rack space available

Common Questions

What Input Voltage Does It Need?

It's built for negative 48 VDC battery systems, with an operating range of 41 to 60 VDC negative. Low battery shutdown is -40.2V and high input voltage shutdown is -61.0V.

How Do I Set Up Monitoring on a PC?

Connect the RS485 port to the PC through an RS485 to USB converter. AIMS lists 19200 bps, 8 data bits, no parity and no flow control, with the PC as master and the inverter as slave. Each inverter's RS485 ID is 1 by default and can be set from 1 to 99 by holding the UP button while turning on the power.

Can It Run Without Utility Power Connected?

Yes. With the city power breaker off, the inverter runs in inverter-only mode and supplies AC power from the battery as long as the DC supply provides enough voltage.

What Warranty Does It Have?

AIMS lists a 2-year warranty for this inverter.
