Delta · Modulon DPHDelta Modulon DPH Three-Phase UPS

Overview

The Delta Modulon DPH is a three-phase UPS series for critical loads, data centres, healthcare, industrial and infrastructure. We specify the right configuration from the Modulon DPH line, supply it, and install it turnkey across Canada. We carry every major brand, so we can compare the Modulon DPH against the alternatives on price, footprint and lead time.

How a three phase double conversion UPS carries the load, and where the bypass sits.

Specifications

Density & light-load efficiency

The Modulon DPH is Delta's MW-class modular UPS, built from 50 kW power modules, Delta calls it the highest power density in its class. It's tuned for the way data centres actually run: 95% AC-AC efficiency at 30% load and a flat 96% above 50% (up to 96.5%), with unity power factor (kVA = kW) and low input THD. In a single rack it scales vertically from 25 kW to 200 kW with N+1 or N+X redundancy, and up to four units parallel for more, a pay-as-you-grow path from TIA-942 Tier 1/2 toward Tier 4. North America: 300 and 500 kVA at 480 V.

Fault tolerance & service

Power, control and static-transfer modules are all hot-swappable, keeping mean-time-to-repair close to zero and saving 50% or more of repair time versus a standalone UPS. The DPH is self-redundant, full control logic self-synchronises and switches to backup on a module failure, with redundant auxiliary power so a mains loss can't take down the control system. It supports N+1, hot-standby (dual input) and 2N/2N+1 configurations.

Sizing, redundancy and custom builds

We engineer the solution: load and growth analysis, redundancy (N, N+1, 2N), runtime and battery sizing, paralleling and switchgear, and custom configurations where the standard catalogue doesn't fit. Because we supply every major brand, the Modulon DPH is one option we weigh on its merits, not the only answer.

Supply, install and lifecycle

We deliver, install and commission the system on site (coordinated with your electrical contractor), then keep it running with preventive maintenance, battery replacement and emergency support, including Modulon DPH units that are out of warranty or discontinued by the manufacturer.

Common questions

Can you replace an old or discontinued unit with a different brand?

Yes, that's most of what we do. Send the model and part number you have (any brand, even end-of-life) and we cross-reference an equivalent that matches the load and footprint. If the original is back-ordered, we propose an in-stock unit that ships sooner.

Do you replace just the batteries, or the whole UPS?

Whichever is the better value. A battery replacement (sometimes with an added cabinet for more runtime) often restores full protection at a fraction of a new system. We need your exact model and variant to quote it accurately.

What are the lead times?

It depends on the model and stock. When the original has a long lead time, we usually propose an equivalent we can ship sooner so the load isn't left exposed. Tell us your timeline in the quote.

Do you install it, and across Canada?

Yes, we supply, install and commission the system anywhere in Canada, coordinated with your electrician, and maintain it afterward: preventive maintenance, batteries, emergency support and remote monitoring, on a single unit or a multi-site fleet.

Can you quote a complete system, not just the UPS?

Yes, UPS, power distribution, racks, batteries and the installation in one quote, coordinated with your electrical contractor.
