FAQ: Telecom Base Station & Industrial UPS Guide
Last updated 2026-08-25
Telecom base stations and industrial facilities have unique power requirements — 48V DC battery plants, wide temperature swings, and the need for remote management. This FAQ covers High Idea Power’s specialized telecom and industrial power solutions, from 48V rack-mount UPS to industrial frequency inverters.
1. What solutions does High Idea Power offer for telecom base stations?
Telecom base stations typically operate from a 48V DC battery plant. High Idea Power provides two families:
E Series — 48V Communication UPS (1–3KVA): Online double-conversion units accepting 48V DC input from existing battery banks, delivering pure sine wave 220VAC. Key features: DC cold start, auto-restart on AC return, RS232 + dry contact interface, surge/lightning protection, 19-inch rack-mount (2U).
H Series — 48V Communication Inverters (1–3KVA): Pure sine wave inverters accepting 36–60V DC input. H1K-48 (1000VA/800W, 432×88×350mm, 8.5 kg) and H3K-48 (3000VA/2400W, 432×88×440mm, 11.5 kg). Wide AC input range of 115–300V, output 220VAC ±3%.
2. What about 110V and 220V DC industrial applications?
High Idea Power’s H series supports all three DC voltage standards:
| Model | DC Input | Max DC Current | AC Input Range |
|---|---|---|---|
| H1K-48 | 36–60V | 19.6A | 115–300V |
| H1K-110 | 90–130V | 8.6A | 172–268V |
| H1K-220 | 180–280V | 4.3A | 172–268V |
| H3K-110 | 90–130V | 25.8A | 172–268V |
| H3K-220 | 180–255V | 12.9A | 172–268V |
All produce pure sine wave 220VAC ±3%, with LCD/LED display and RS232 + intelligent expansion slot.
3. Which products serve high-power industrial UPS needs?
- H6K-220 / H10K-220: 6–10KVA power inverters (180–280V DC), 2U rack-mount (454×438×178mm).
- HTT Series — Industrial Frequency UPS (6–120KVA): Transformer-based online double-conversion with galvanic isolation for factories, mining, and heavy machinery.
- HTB Series — Industrial Rack-Mount Inverters (500VA–12KVA): Industrial-grade transformers for railway signaling and petrochemical instrumentation.
4. How does the E series handle remote site challenges?
- DC cold start: Powers up from 48V batteries alone — critical for site commissioning.
- Auto-restart on AC return: Resumes normal operation without manual intervention.
- Wide temperature tolerance: -10°C to 40°C, covering unheated shelters.
- Surge and lightning protection: Built-in for exposed tower sites.
- Front-access maintenance: All connections and displays accessible from the front panel.
5. Can these integrate with existing telecom NMS?
Yes. Both series provide RS232 serial, dry contact outputs for BMS/SCADA alarm panels, intelligent expansion slots for SNMP cards (TCP/IP integration), and optional Smart UPS cloud monitoring with web-based dashboards for real-time status and event logs.
6. Industrial frequency vs. high-frequency UPS — what’s the difference?
| Feature | Industrial Frequency (HTT) | High-Frequency (E/ET) |
|---|---|---|
| Transformer | Built-in isolation transformer | Transformerless |
| Galvanic isolation | Yes (input-output) | No |
| Inrush handling | Excellent (motors, pumps) | Standard (electronic loads) |
| Best application | Factories, railways, heavy machinery | Data centers, telecom, IT |
7. How do I select the right DC voltage variant for my site?
- 48V DC — Standard in telecom towers. Choose E1KS/E2KS/E3KS-48 or H1K/H3K-48.
- 110V DC — Electric utility substations, railway signaling. Choose H1K/H3K-110.
- 220V DC — Large utility installations, industrial plants. Choose H1K/H3K-220 or H6K/H10K-220.
For sites without existing DC plant, ET series Lithium Battery UPS with built-in batteries or LD series external packs provide a complete, self-contained solution.
