淘宝京东找了一圈全是220V输入的，想看看哪有110V输入的，感谢。不是很想用改的服务器电源，出问题没有条件折腾。。。

求4官网写的带110，但是我的后面写的220，可以问问厂家

@"BH9DFB_AI6YY"#p67604 求精一样是开关电源，我宁可用明纬，服务器电源不容易出问题的，我身边求精坏的不少，拆开看了用料甚至没明纬电源的结构好

@"BG5DZG"#p67610 我自己用的就是明纬的开关电源，很稳定我一直开着给我电台供电的作为链路台电源

楼主不在西恩可以在日亚或者美亚上看看ALINCO DM-330 这个有AC100-120V输入的版本

@"BG6UFA"#p67615 看了…DM330啥都好就是太贵了200刀，他家便宜的dm30也要一百多刀，钱包顶不住🥲

@"BI1IZF"#p67639 这个电源与戴尔那款18A的电源相比，电磁干扰怎么样？？？

买个正品明伟（明纬？）有110/220开关

@"BI1IZF"#p67639 这个短波噪音怎么样啊，看手册Ripple都到150mVpp了

@"BG6UA"#p67643 不太了解戴尔18A那个，没使用过

@"BH9DFB_AI6YY"#p67648 同使用的人 5100 7300 建伍710 并没有什么问题，并且他标注的是最大纹波噪声，求精和钻石电源都不标注最大纹波噪声，空载情况下纹波噪声当然更低如果你非要针对所谓的电台电源这回事，那就只能是台湾纳胜NS-1230系列，纹波小于100mV，支持110和220V，不过大陆溢价比较高，都当传家宝，二手的都四百多，反正是比钻石便宜，纳胜其他几个系列也都不错，但是大陆都买不到，如果你看过他们产品表你会发现求精和他长得一样 https://meterexpert.com/products/power-supply/

Does Qingjing have a radio power supply that supports 110V input at the same price point?

BH9DFB_AI6YY

I searched on Taobao and JD, but all of them only accept 220V input. I'm wondering if there are any that accept 110V input. Thanks. I don't really want to modify the server power supply, because if it malfunctions, I won't be able to fix it...

BG5DZG

BH9DFB_AI6YY Just like the "Qing Jing" power supply, which is a switching power supply, I prefer to use Ming Wei power supplies. Server power supplies are generally more reliable, and I've seen many Qing Jing units fail. When I disassembled them, I found that the components were often of poor quality, and even some Ming Wei power supplies had better designs.

PPPPPAN

Could you please provide the information from the official 4 website that mentions "110", but I have written "220" after it? Can I ask the manufacturer about this?

BG5DZG

BG5DZG I personally use a Mingwei power supply, which is very stable. I've been using it to provide power for my radio station, and it works perfectly as a line-powered source.

BI2QEA

BG5DZG So, does your voltage supply meet the requirements? The power source isn't 12V, is it?

BG6UFA

The original poster suggests checking for ALINCO DM-330 at retailers like Yodobashi Camera or Amazon Japan.

This version has an input of AC100-120V.

BH9DFB_AI6YY

BG6UFA I looked at the DM330, and it seems great overall, but it's too expensive – $200. Even their cheaper DM30 costs over $100, which is not affordable for me.🥲

BI1IZF

求精质量不行，钻石太贵，目前推荐身边几个人都用明纬的ENP-360-12，专门为通信设备设计的，各种安规电磁认证拉满。

输出 13.8V 26A

输入90-264VAC，127-370VDC

常规短波 100瓦发射还是没问题

BG6UA

BI1IZF How does the electromagnetic interference of this power supply compare to Dell's 18A power supply?

BH9DFB_AI6YY

BI1IZF What do you think of this shortwave noise? The ripple is already at 150mVpp, according to the manual.

BI1IZF

BG6UA I'm not very familiar with the Dell 18A; I haven't used it before.

Bi4KKF

BG6UA I used to use Dell's 18A BBA power supply before. As for the UV section, there was still a voltage drop. Shortwave communication was also possible, but the output power was insufficient. Server power supplies are really great!

BH9FPK

I want to buy an authentic Mingwei (Mingwei?) with a 110/220 volt switch.

BI1IZF

BH9DFB_AI6YY Users who also use the 5100 and 7300 models, along with the Kenwood 710, report no issues. He specifically mentions that the maximum ripple noise is indicated, while neither "求精" nor "钻石电源" indicate a maximum ripple noise value. Naturally, the ripple noise will be lower in an unloaded state.

If you insist on focusing solely on the "radio power supply" issue, then the Taiwanese Nansheng NS-1230 series is the best option. It has a ripple of less than 100mV and supports both 110V and 220V. However, mainland China has a significant price premium, and they are often treated as heirlooms, with used ones costing over 400 yuan. Even though they are cheaper than diamonds, other Nansheng series are also good, but you can't find them in mainland China. If you have seen their product specifications, you will find that "求精" looks very similar to the NS-1230.

BH9DFB_AI6YY

BI1IZF Indeed, the Alinco Nash and Astron power supplies all look very similar. Thinking carefully, I don't understand why the quality of Mingwei should be worse than others at the same price point. I have already purchased the ENP360, thank you!

BG6DRU

I need support from the "Jing Eight Generation" community. You can search for me on some platform, and I will provide more details.

BH9DFB_AI6YY

I have received the goods and would like to report the following: There is interference in the amateur band frequencies of 7098, 21031, and 29495 when operating ENP-360-12 with a dummy load. The interference affects approximately 1 kHz bandwidth at each frequency point; The RTTY test at 70W produced no heat in one minute; Finally, as is common with switching power supplies, there is a faint but distinct noise when the device is operating without a load.

The only thing I find uncomfortable is the distinct clicking sound that accompanies the CW transmission from the ENP, which I suspect is caused by a loose inductor coil inside. I'm not sure if this is a problem specific to my unit or a common issue.
@BI1IZF I was wondering if you experience this as well, thank you.

BH9DFB_AI6YY

BH9DFB_AI6YY By the way, the interference shouldn't be coming from the power supply.😅

BH6BEX

BH9DFB_AI6YY 我也买了这台，刚到手测试了一下，CW也是有这个咔哒声，估计是继电器的声音吧，听着不舒服

BI1IZF

I am currently looking for a HAM operator with a similar power supply to perform CW testing. I will reply later, but I don't have a radio on hand that can operate in CW mode.

BG5DZG

BI2QEA Yes, it's adjustable. I was able to fine-tune it to around 13.6V, and in some cases, I could even get it to 13.8V. However, I found that maintaining a stable 13.6V worked best for me.
