Description  

Samlex PSR-2200-48 - 2200W Pure Sine Wave Rack Mount Inverter with Transfer Relay, 48V

Telecom standardized on 48 volt plants for a reason: more power over thinner copper. The Samlex PSR-2200-48 takes that 48V bus straight to 2200 watts of 120VAC pure sine power in a 2U rack chassis. Its built-in 30 amp transfer relay keeps the load on commercial power until the input fails, then hands it to the inverter, so your AC-fed equipment runs from the same battery string that already floats the DC side of the site.

Warranty

Warranty. Samlex America warrants the PSR-2200-48 for 2 years. Full terms are confirmed in writing with your quote.

Made for the 48 Volt Bus

40 to 60 VDC window
The input range spans a 48V string from deep discharge through equalize charge, so normal plant behavior never trips a shutdown.
Over 92% peak efficiency
The highest-efficiency model in the PSR line by Samlex's own ratings. At 48 volts the same output moves half the DC current of a 24 volt feed: thinner conductors, less heat in the cabinet.
Transfer on your terms
Synchronized transfer phase-locks the inverter to the incoming AC before switching; unsynchronized transfer is there for sources that cannot be matched.
  • Pure sine wave, under 2% THD; output selectable 100 to 120 VAC and 45 to 65 Hz.
  • Load Safe algorithm pulls the load off a browning-out grid before equipment resets.
  • NOC visibility built in: Ethernet web page, SNMP traps, e-mail alerts, USB command-line setup.
  • AC input cord supplied (IEC C19 to NEMA 5-20P); NEMA 5-20R duplex output; 12 A input breaker.
  • ETL listed to UL 62368-1 and CSA C22.2 No. 62368-1; FCC Part 15(B) Class B.

Where This Inverter Is Used

  • 48V telecom plants and base stations - AC-fed equipment powered from the string that runs the site.
  • Traffic and public safety infrastructure - intersections and roadside cabinets that cannot drop during an outage.
  • Mobile command and response units - rack AC from a 48V vehicle bank.
  • Data centers with 48V distribution - a protected 120VAC circuit without a standalone UPS.

Ordering

Fit check. Ships as one parcel. Sites drawing under 1200 watts can use the 1U PSR-1200-48 for less money and less rack; 24 volt plants take the PSR-2200-24 instead. For multi-site quantities, send ZIPs and counts and a battery specialist will return a written quote in 24 to 48 hours.

Frequently Asked Questions

Will it run from my 48 volt battery plant?

It accepts any nominal 48V bank whose voltage stays between 40 and 60 VDC, which covers float and equalize on lead-acid strings and the working range of 48V lithium racks. Confirm your plant's grounding arrangement against the product manual before ordering, or send us the plant details and we will check it for you.

PSR-2200-48 or PSR-2200-24?

Same output, chassis and relay; choose by the plant you have. The 48 volt version runs at higher peak efficiency and its internal fusing totals 90 amps against the 24 volt model's 150, because the same power arrives at half the current.

Can it feed the load from the inverter full-time?

Yes. Online mode makes the inverter the primary source and holds the grid in standby, which suits sites where raw utility power is too unstable to feed equipment directly.

Does a 48V solar system work with it?

A 48V off-grid bank sits inside the input window, and the AC input can take a generator so the transfer relay manages generator handoffs. That gives a solar site grid-quality AC with an automatic fallback path.

Put your 48V plant behind the whole rack.
