/// Critical_Issues

Price per second without electricity

The Ukrainian power system has experienced unprecedented damage of 2022 years. Blackouts, voltage sags and unstable frequency have become the norm. For critical facilities, every millisecond without power is a threat to life and business.

Hospitals: a threat to life

Operating rooms, ventilators, resuscitation - even 20 ms without power resets the settings of critical equipment. A linear-interactive UPS has a switching time of 4-12 ms — this is unacceptable for medicine.

Production: destroyed batches

Extruders, pharmaceutical lines, chemical reactors — a stoppage for 0.5 seconds destroys tens of thousands of dollars worth of raw materials. Restarting the line takes an hour.

Data centers: data loss

Servers, DBMS, active network equipment - improper shutdown leads to damage to file systems, loss of transactions and breach of SLA to clients.

/// UPS_Solution

Online UPS: the real zero

Online UPS of double conversion is the only topology that provides TRUE ZERO transfer time. The load is always powered by the inverter and not directly by the grid.

0 ms switching

Double conversion: AC→DC→AC. The load is always on the inverter. Switchover Time is not required - the load simply does not notice the network failure.

Compatibility of generator

The generator emits a "dirty" frequency (47-53 Hz). Online UPS accepts it as an input and outputs a perfect sine wave of 50 Hz ± 0.1% at the output. No sync issues.

N+1 reservation

Modular architecture: up to 8 UPSs in parallel. Hot-swap modules 20/30/50 kVA — replacement without disconnecting the load. One module is always redundant.

/// Battery_Comparison

Why lead for industrial UPS?

The UPS works in standby mode: 99.9% of the time it is recharging, and only a few times a year it supplies energy. This is a fundamentally different usage profile than BESS for Peak Shaving.

Parameter Lead (VRLA AGM/GEL) LiFePO4
CAPEX ($/kWh) $120-180 $280-400
Cyclic resource 300-500 cycles 3000-6000 cycles
The real load in the UPS 5-20 cycles/year — the resource is enough 5-20 cycles/year is a redundant resource
Service life (standby) 5-12 years (GEL up to 15) 15-20 years
BMS complexity Not needed — simple charging Mandatory, cell balancing
Compatibility of existing infrastructure Full — standard 30+ years May need a new charger
Weight / Area Heavier, larger footprint Lighter, more compact
Utilization 99% recyclable, a developed network More difficult disposal

The conclusion of the engineering department

For UPS applications (low-cycle mode, long standby), lead VRLA batteries remain the optimal choice based on the cost/efficiency criterion. Lithium is appropriate only when the battery area of ​​the room is limited or there is a need for an extremely long service life (15+ years). We design solutions for both types of batteries and help choose the best option.

Frequently Asked Questions

Linear interactive The UPS supplies the load directly from the network and switches to the battery in the event of a failure (switching time 4-12 ms). Online (Double Conversion) always converts the input power: AC→DC→AC. The load is continuously supplied by the inverter, so the switching time = 0 ms. Also, the online UPS completely isolates the load from network interference, voltage surges, and unstable frequency. For industrial facilities and medicine, this is the only acceptable option.
Autonomy is determined by the capacity of the battery bank, not by the power of the UPS. For a 100 kW load: 10 minutes requires ~25 kWh (21 units 12V/100Ah), 30 minutes — ~75 kWh (63 units), 1 hour — ~150 kWh (125 units). The cost of a battery bank for 30 minutes for 100 kW is approximately $9,000-12,000. The exact calculation depends on the load profile (constant vs variable) and the permissible depth of discharge.
VRLA AGM — every 5-7 years at a temperature of 20-25°C. VRLA GEL — every 8-12 years. Every +10°C above 25°C cuts the resource in half (Arrhenius rule). Therefore, the design of the AKB room with air conditioning is a critical factor. We include thermostatic control in every project. Battery replacement is performed block by block without disconnecting the load (if bypass is available).
Yes, an online UPS is the ideal partner for a generator. A typical scenario: the network disappears → the UPS instantly takes over the load → after 10-30 seconds the generator is started → the UPS switches to power from the generator and charges the battery. Since the Online UPS converts any input (frequency 40-70 Hz, voltage ±20%), it "cleans" the unstable output of the generator. A linear-interactive UPS may not synchronize with the generator and remain on batteries.
Quarterly: visual inspection, checking the room battery temperature, checking the event log. Annually: load test discharge (battery runtime test), terminal tightening check, fan dust filters replacement, monitoring calibration. Every 3-5 years: impedance testing of each battery unit to identify weak elements. We offer service contracts 24/7 of SLA for a response time of 4 hours.
