Uninterruptible Power Supplies (UPS)
A mains interruption of a few seconds can cost a plant hours: PLCs lose state, servers running WMS or SCADA shut down uncleanly, and access and fire systems drop offline. An uninterruptible power supply bridges the gap, conditioning the incoming supply and carrying the connected load on batteries until generators start or the mains returns. Listings on Machinery Masters run from 500 VA desktop units for a single workstation, through rack and tower Smart-UPS systems around 1 to 3 kVA, to three phase plant such as a 40 kVA APC MGE Galaxy. You compare ratings and battery condition across live listings and deal with each seller directly.

Uninterruptible Power Supplies (UPS) Product Types
UPS systems divide by topology, how the unit sits between the mains and the load, and by rating. These are the main types listed.
Desktop and tower UPS units
Compact line-interactive units from around 500 VA to 1500 VA that protect a workstation, till or small control panel. They switch to battery in milliseconds and give minutes of runtime for a controlled shutdown.
Rack-mount and line-interactive UPS
Units in the 1 to 3 kVA class, such as the APC Smart-UPS RT series, built for 19 inch comms cabinets. Automatic voltage regulation trims sags and surges without draining the battery, and network cards allow remote monitoring.
Online double-conversion UPS
Systems that rebuild the output waveform continuously from the battery bus, so the load never sees the raw mains. The standard choice for sensitive instrumentation and control equipment on sites with poor supply quality.
Three phase UPS systems
Floor standing plant from around 10 kVA to 40 kVA and beyond, such as the APC MGE Galaxy and ABB Power Wave ranges, carrying whole control rooms or server rooms. Installation needs a dedicated supply and commissioning by a competent electrician.
Power conditioners
Units from manufacturers such as Powervar that filter noise and regulate voltage without a large battery bank. Fitted where the problem is supply quality rather than outages, often in front of instrumentation and metrology equipment.
Brands on Machinery Masters
APC by Schneider Electric dominates the small and mid range, with Powervar, ABB, Kohler and Powertecnique appearing on conditioning and three phase duties. Brands shown here hold live UPS listings on Machinery Masters, so the strip reflects genuine availability.

Pourquoi choisir Machinery Masters
Uniquement des vendeurs vérifiés
Chaque vendeur est vérifié avant la mise en ligne de la moindre annonce. Machinery Masters contrôle également l'exactitude des annonces, afin que les acheteurs puissent investir en toute confiance dans des machines de grande valeur.
Portée mondiale
Les annonces proviennent de vendeurs de toute l'Europe, d'Amérique du Nord et d'ailleurs. Cette portée élargit le choix au-delà de tout réseau régional de revendeurs, et c'est souvent le seul moyen de trouver des modèles qui ne sont plus fabriqués en bon état.
Options de financement flexibles
Les annonces éligibles bénéficient d'un financement par l'intermédiaire de partenaires. Les conditions sont affichées directement sur les pages produit concernées, ce qui permet d'étaler le coût au lieu d'épuiser votre fonds de roulement en une seule fois.
Contact direct avec le vendeur
Aucun intermédiaire entre l'acheteur et le vendeur. Renseignez-vous sur l'historique d'entretien, organisez des inspections et négociez directement avec la personne qui connaît réellement la machine.
Applications and Uses
A UPS earns its place wherever an uncontrolled power loss costs more than the unit does. These settings account for most of the demand.
Warehouse IT and comms rooms
Rack-mount UPS units hold up the servers, switches and scanners a 3PL or distribution site runs on. Even a short dip that reboots the WMS can stall picking across the whole shift.
Process control panels
Line-interactive and online units keep PLCs, HMIs and safety circuits alive through interruptions, so a line restarts from a known state instead of a crash. Sizing covers the panel load plus margin for inrush.
Plant rooms and building services
BMS controllers, fire panels and access control systems stay live on UPS power while generators start. Facilities teams typically standardise on one range so batteries and spares interchange across the site.
Workshops and test benches
Smaller tower units protect CNC controllers, test instruments and bench equipment from the sags and spikes common on industrial supplies shared with heavy switching loads.
Benefits from Machinery Masters
UPS purchases are usually either urgent replacements or planned protection projects, and the marketplace serves both.
01
The full rating range in one place
Desktop units, rack systems and 40 kVA three phase plant sit in one category, so you match the UPS to the load rather than to what one dealer happens to stock.
02
Serious savings on battery-swap kit
A UPS is largely electronics that age slowly around batteries that age fast. A used unit with fresh batteries performs as new at well below list price, and batteries are a routine consumable.
03
Condition confirmed before commitment
Battery age, runtime under load and fault history are questions the seller can answer directly from the listing, before you spend money or schedule an electrician.
Frequently Asked Questions sur Uninterruptible Power Supplies (UPS)
Add up the load of everything the UPS must carry, in watts or VA from each item's rating plate, then add around 25 percent headroom. Next decide the runtime you need at that load: minutes for a clean shutdown, longer if the UPS must cover generator start. Quote both figures in your enquiry so the seller can confirm the match.
Battery age first: VRLA batteries last three to five years, so assume replacement unless the seller shows recent install dates. Ask for a runtime test under load, check the fault log via the front panel or network card, and confirm the input plug or hardwire arrangement suits your supply. Budget batteries into the price before you compare listings.
A line-interactive UPS passes the mains through with voltage regulation and switches to battery when it fails, with a transfer time of a few milliseconds. An online double-conversion UPS rebuilds the output continuously, so the load never sees a transfer at all. Control systems and instrumentation on poor supplies justify online; general IT loads rarely do.
Systems like a 40 kVA Galaxy need a dedicated three phase supply, a maintenance bypass arrangement and floor space with ventilation for the unit and battery cabinet, which together can weigh over a tonne. Commissioning is an electrician's job, not a plug-in. Confirm dimensions, weight and battery configuration with the seller before planning delivery and access.
Usually yes. Most UPS ranges, including the APC Smart-UPS and Galaxy families, use standard VRLA blocks or documented battery cartridges that third party suppliers still make. Check the battery part reference against current availability before buying, and ask the seller whether the unit reports battery status, which makes future replacement a planned job rather than a surprise.
