Quick Verdict
If your cabinet needs 30 kW of controlled power and you can work with a used, tested unit, the REXROTH HMV01 is the right investment despite its USD 2,474.68 price. If you are wiring a small control circuit with modest load requirements, the HPS PH100MQMJ at USD 76.82 is the sensible choice for small control loads.
At a Glance

| Power | 30 kW output | 100 VA |
| Frequency | 48-62 Hz | 50/60 Hz |
Where the Rexroth Wins
The REXROTH HMV01 is the clear choice when your application demands a real power supply rather than a passive transformer. Its 30 kW output and 400-480 V input range put it in a different class from a 100 VA control transformer. The condition is listed as Used & Tested, and the package includes a 2-year warranty, 60-day money back, and lifetime professional support, which matters when you are committing over $2,400 to a critical line. If your control system is built around a Rexroth HMV-series supply, this is the matching part.
Where the HPS Wins
The HPS PH100MQMJ is the sensible pick for low-voltage control circuits that only need a small transformer. Its USD 76.82 price sits at the opposite end of the range from the Rexroth's USD 2,474.68, and it is not a replacement for a 30 kW supply. The 100 VA capacity is adequate for pilot lights, contactor coils, and small relay loads. It comes as New - Open box, mounts to the panel, and uses screw terminals for straightforward wiring. If your machine tool or control panel already has a 240x480V feed and needs a compact control transformer, this HPS gets the job done without a large price commitment.
Product Notes
Used & Tested REXROTH HMV01.1E-W0030-A-07-NNNN Control Power Supply
This is a serious piece of automation gear. The HMV01.1E-W0030-A-07-NNNN is a control power supply rated for 30 kW of output, designed to run on a 400-480 V input at 48-62 Hz. It is sold as Used & Tested, meaning you are getting a working unit rather than a pull from an unknown source. The included 2-year warranty, 60-day money-back guarantee, and lifetime professional support add a layer of protection you rarely see on used industrial electronics. The trade-off is price and condition: at USD 2,474.68, it represents a major investment, and it is not the right tool if you only need a small control transformer.
HPS PH100MQMJ 100VA Industrial Control Transformer
For a very different job, the HPS PH100MQMJ is a compact 100 VA industrial control transformer in New - Open box condition. It is rated for 50/60 Hz operation and uses a panel-mount design with screw terminals, making it straightforward to integrate into a control cabinet. At USD 76.82, its price is the lower one in this comparison. The main limitation is the 100 VA capacity: this transformer is not designed to power a drive, motor, or high-draw load. It belongs in a circuit with small control loads that need reliable power conversion. If your application fits that profile, this is a straightforward way to get a branded HPS component into your panel.
Final Choice by Use Case
Choose the REXROTH HMV01.1E-W0030-A-07-NNNN if your line needs 30 kW of controlled power, you have 400-480 V available, and a tested unit with warranty support justifies the USD 2,474.68 price. Choose the HPS PH100MQMJ 100VA if you are wiring a small control panel and want a USD 76.82 transformer with screw terminals and open-box new condition. The two are not interchangeable; match the power stage to the load.
