When you're shopping for industrial power supplies and transformers, the decision often comes down to two very different component types: a control power supply and a control transformer. The REXROTH HMV01.1E-W0030-A-07-NNNN is a used and tested control power supply with a high output rating, while the Square D 9070TF100D1 is a new industrial control transformer at a much lower price. Which one fits your cabinet depends on the power your system actually needs.
Quick verdict
If your control application demands a high-output power supply and you're prepared to pay for it, the REXROTH HMV01.1E-W0030-A-07-NNNN is the stronger candidate. If you want a new transformer for a conventional control circuit and want to keep the outlay far lower, the Square D 9070TF100D1 is the practical choice. The two components solve different problems, and the clear price gap reinforces that difference.

Where each product wins
- REXROTH HMV01.1E-W0030-A-07-NNNN wins for applications that need a high-output control power supply. It accepts 400 to 480 V input, delivers 30 kW output power, and runs at 48 to 62 Hz. The package also includes a 2-year warranty and a 60-day money-back guarantee, which adds reassurance to a used purchase.
- Square D 9070TF100D1 wins for new transformer needs on a tighter budget. It's a brand-new industrial control transformer from Square D, with a listed price that is over $2,000 below the Rexroth. If a control transformer is the correct component for your panel, this is the lower-cost route.
Product notes
REXROTH HMV01.1E-W0030-A-07-NNNN
If your control system genuinely needs a 30 kW power supply, the REXROTH HMV01.1E-W0030-A-07-NNNN brings that muscle. It accepts 400 to 480 V input, runs at 48 to 62 Hz, and comes with a 2-year warranty and a 60-day money-back guarantee, which is useful for a used unit. The trade-off is the outlay: this is the higher-priced option by a wide margin, and the used condition means the component has prior service. For replacements in an existing high-power design, the tested condition and warranty offer a way forward, but the cost is significant.
Square D 9070TF100D1
For a new transformer that costs far less, the Square D 9070TF100D1 is the clear pick. It's a brand-new industrial control transformer with the MPN 9070TF100D1, and its listed price sits far below the Rexroth. If your panel calls for a transformer rather than a power supply, this unit fills that role at a modest cost. The catch is that a control transformer can't match the high output of the Rexroth, so it's not a substitute for the high-power supply. It's the right choice only when a transformer is actually what your circuit needs.
Final choice by use case
For a high-output control power supply requirement, the REXROTH HMV01.1E-W0030-A-07-NNNN is the only one of these two that can deliver that level of power. It's the choice for systems that demand serious output, and the included warranty helps offset the used condition. For a new industrial control transformer at a far lower price, the Square D 9070TF100D1 is the obvious selection. If your application is a standard control transformer duty and you want new hardware, the Square D is the lower-cost route. In short: match the component to the need-high power supply for high-power systems, new transformer for standard control voltage stepping.
