About SOLAHD

SolaHD is a manufacturer of power quality and power conversion equipment, with a product history that includes the development of constant-voltage transformers and ferroresonant power conditioning technology. The brand's catalog spans several functional categories: power conditioners, surge protective devices (SPDs), uninterruptible power supplies (UPS), and DC power supplies. These products are used in industrial, commercial, and institutional electrical systems where voltage regulation, surge suppression, and backup power are required. SolaHD equipment is commonly specified for automation panels, process control systems, and facilities with sensitive electronic loads. 3G Electric supplies the SolaHD line globally, offering technical selection support and access to the product families described below.

The product range includes single-phase and three-phase power conditioners, both panel-mount and floor-standing configurations. Panel-mount units, such as the 3 kVA model (SKU 5EU18), accept input voltages from 110 to 415 V AC and provide regulated output from 110 to 240 V AC at up to 25 A. These hardwired conditioners are used to protect control systems from sags, swells, and transients. For surge protection, SolaHD offers chase-nipple external-mount SPDs in metal enclosures. Single-phase versions (e.g., SKU 19L438) are rated for 240 V AC with a maximum continuous operating voltage (MCOV) of 320 V AC. Three-phase models cover 480 V AC Delta (SKU 19L440) and 120/208 V AC Wye (SKU 19L441) systems, with MCOV ratings up to 575/640 V AC and 1,000 V AC respectively. These SPDs are designed for external mounting via a chase nipple, simplifying installation on electrical enclosures.

The UPS portfolio includes both AC and DC input configurations. Standby UPS systems with hardwired connections are available in 500 VA and 850 VA ratings (SKUs 61KP82 and 61KP83), operating at 120 V AC input and output. These units provide backup power and voltage regulation for industrial control panels, PLC systems, and similar equipment. DC input UPS systems, such as the SDU1024B (240 VA) and SDU2024B (480 VA), accept 23–30 V DC input and deliver regulated 23–30 V DC output, supporting continuous DC power backup for industrial applications. All SolaHD products are built to applicable industry standards, with metal enclosures on SPDs and hardwired terminations on many models. 3G Electric maintains inventory and provides technical documentation to support specification and procurement.

Common Applications

  • Industrial automation — SolaHD panel-mount power conditioners (e.g., SKU 5EU18) regulate voltage for PLC and control systems.
  • Electrical distribution — SolaHD chase-nipple SPDs (e.g., SKU 19L438) protect 240 V AC single-phase circuits from transients.
  • Three-phase power systems — SolaHD SPDs (e.g., SKU 19L440) safeguard 480 V AC Delta equipment in manufacturing plants.
  • Control panels — SolaHD standby UPS systems (e.g., SKU 61KP82) provide backup power for hardwired 120 V AC control circuits.
  • DC power backup — SolaHD DC input UPS systems (e.g., SKU 61VD24) maintain 24 V DC power for industrial control and instrumentation.
  • Commercial facilities — SolaHD SPDs (e.g., SKU 19L441) protect 120/208 V AC Wye distribution in buildings with sensitive electronics.

Frequently asked questions

Common questions about SOLAHD from 3G Electric.

What is the difference between SolaHD power conditioners and SolaHD UPS systems?

SolaHD power conditioners regulate AC voltage and filter transients but do not provide backup power during an outage. They are typically panel-mount or floor-standing units, such as the 3 kVA model (SKU 5EU18), which accepts 110–415 V AC input and delivers regulated 110–240 V AC output. SolaHD UPS systems, including the SDU500B and SDU850B, provide battery backup and surge protection for connected equipment. Selection depends on whether the application requires voltage regulation only or also needs ride-through during power loss.

What are the input and output voltage ranges for SolaHD DC input UPS systems?

SolaHD DC input UPS systems, such as the SDU1024B (240 VA) and SDU2024B (480 VA), accept 23–30 V DC input and provide regulated 23–30 V DC output. These units are single-phase standby UPS systems designed for continuous DC power backup in industrial applications. They are suitable for 24 V DC control circuits and other low-voltage DC equipment that requires uninterrupted power. The output is regulated to maintain stable voltage within the specified range.

What surge protection ratings are available in SolaHD chase-nipple external-mount SPDs?

SolaHD chase-nipple external-mount SPDs are available for several system voltages. The single-phase model (SKU 19L438) is rated 240 V AC with a maximum continuous operating voltage (MCOV) of 320 V AC and a surge capacity of 1000 V (L-L)/1200 V (L-G). Three-phase models include the STV100K48D for 480 V AC Delta systems (MCOV 575/640 V AC, 2000 V L-G/L-L) and the STV100K10Y for 120/208 V AC Wye systems (MCOV 1,000 V AC, 1000 V L-L/600 V L-N/700 V L-G, N-G). All are housed in metal enclosures for external mounting via chase nipple.

Can SolaHD power conditioners be used in three-phase applications?

SolaHD offers both single-phase and three-phase power conditioners. The sample product listed here (SKU 5EU18) is a single-phase panel-mount unit rated 3 kVA. For three-phase applications, SolaHD provides other models in its catalog. Selection depends on the system configuration, load requirements, and available panel space. 3G Electric can assist with identifying the appropriate model based on input voltage, output voltage, and power rating.

What are typical applications for SolaHD SPDs and UPS systems?

SolaHD SPDs are used to protect electrical distribution systems and sensitive equipment from voltage transients. Chase-nipple external-mount models are often installed on enclosures in industrial facilities, commercial buildings, and institutional settings. SolaHD UPS systems, such as the SDU500B and SDU850B, provide backup power for industrial control panels, PLC systems, and other hardwired 120 V AC equipment. DC input UPS systems support 24 V DC control circuits and similar low-voltage DC loads requiring continuous power.

What enclosure types are used for SolaHD surge protective devices?

SolaHD chase-nipple external-mount SPDs are supplied in metal enclosures. These enclosures are designed for external mounting on electrical panels or equipment via a chase nipple, which allows for secure installation and protection of the internal components. The metal construction provides durability and helps with heat dissipation. Specific enclosure dimensions and materials may vary by model; refer to the product datasheet for exact specifications.
